Supplement to THE COLLIERY GUARDIAN. July 24, 1914 with it. In consequence, the socket opened out and the cage fell to the bottom, fortunately doing little damage. The capel has been replaced by a solid white metal pattern without hoops. The possibility of a similar occurrence at other pits equipped with hooped capels should be considered by all concerned. There were two cases of overwinding while persons were being raised or lowered, and three cases of inrush of water. The most important under the latter heading occurred on December 29, at South Hetton Colliery, Durham. Bord and pillar workings in the Main coal seam were driven towards an area of coal which had formed part of the royalty of the Haswell Colliery, which had been closed down for some years. It was rightly believed that no Main coal had been worked by Haswell Colliery anywhere near this point, but a heading was kept in advance and a certain amount of boring was done until a fault was struck. A hole was also bored some distance into the fault, and then the road was turned to run parallel to the fault, with the view of com- municating with the back heading. About midnight on the day mentioned, while no one was at work in the immediate neighbourhood, water broke in somewhere in the crossheading near the fault and probably from the floor. The feeder rapidly became some 1,100 gallons per minute, and continued at that rate, and it was impossible to get near the inbreak. Temporary dams were hurriedly placed across the two headings in order to direct the water into some lowside workings, and then strong permanent brick and cement dams were built to entirely seal off the water. A pressure gauge placed upon the dams showed a pressure which was being steadily maintained of from 30 to 32 lb. per square inch. Although it is true that no workings in the Main coal seam exist at the other side of the fault anywhere near the inbreak, yet a large area of coal immediately adjoining this point was worked out from the Haswell Colliery in the Low Main coal seam, which lies about 26 fathoms below the Main coal. Inspection of the Old Haswell Colliery plans shows that the fault referred to has a dislocation of 26 fms., which brings the Haswell Colliery workings in the Low Main seam practically level with the workings in the Main coal seam in South Hetton Colliery. All the old workings were known to be full of water, which is doubtless standing at such a level above the dams as is indicated by the pressure upon the gauges. The information regarding Haswell Colliery old workings was available to the management of South Hetton Colliery, and they showed a great lack of foresight in not anticipating and preparing for what actually took place; which events, moreover, under other circumstances might have been attended by most disastrous results. On May 21 last year an alarming outburst of gas occurred in the Harvey seam pit at Trimdon Grange Colliery, Durham. Prosecutions.—Proceedings were instituted in two cases against the agent and the manager of a colliery. Fourteen persons were proceeded against for contraven- tion of regulations with reference to safety lamps ; they were all convicted, and penalties amounting to £14 16s. 6d. were incurred. Fifty-nine persons were proceeded against for contravention of the provisions about matches and smoking. A total of 258 persons were charged, and 253 of them were convicted and mulct in penalties reaching the sum of £239 5s. lOd. This is an extraordinary increase on the previous year, all the figures being rather more than doubled. In 1912, proceedings were taken against 125 persons, of whom 120 were convicted, and the penalties amounted to £109 9s. Coal Mines Act, 1911.—Mr. Wilson says the Act has entailed an enormous amount of work, and has meant the expenditure of large sums of money. It has not only increased the capital charge upon concerns where extensive alterations have had to be made and new apparatus to be provided, but it has also increased the working cost through those sections, the carrying out of which ensure better supervision. The capital charges are not those which are likely seriously to affect the industry; for trade for some considerable time has been buoyant, and has enabled the colliery owners to spend sums of money w’hich in lean years they would have found it much more difficult to produce. It is the permanent rise in working costs which may, in a few short years, cause greater anxiety. The usual solution of lowering wages to suit the state of trade will not in the future play the part that it has done hitherto ; for the economic conditions of the country have altered, and the standard of living has been raised, so that men of all shades of opinion are in general agreement that wages are never likely to drop to the level of 25 years ago. What perhaps is equally true is that the price of coal to the consumer will also not be lowered to that of former years. Upon the surface at mines, in order to conform to the new provisions, probably the greatest expenditure has been incurred in connection with the requirements for reversing the ventilating current. At many mines new fans have been erected either as an addition to the present arrangement, or to take the place of the old. With a few exceptions, arrangements have been made for reversing the air at all mines where mechanical ventilators are in operation. Where this has not been done it is due to a variety of reasons: a new fan having been erected and the motor not delivered ; a long drift to drive from the fan to the downcast shaft; extensive surface alterations, etc. Work, however, is in progress at these places, and shortly every mine will be in compliance. The usual method of reversing is by arranging to convert the fan into a forcing fan, but sometimes by exhausting air direct from the downcast shaft. Water sprays and steam jets are provided in a few instances. Reversal has been tried in many cases with very satisfactory results, but where the means are mechanical ventilators only, most of the managers hesitate to experiment on account of the large areas of goaf which may be charged with gas. There surely would be no insuperable difficulty in experimenting at a week-end or holiday time, when officials only were in the mine to see the results. The information to be gained would be invaluable if ever the occasion arose when it might be deemed necessary to reverse the air. Automatic contrivances to prevent overwinding have now been installed at most of the mines where neces- sary, but there are still a few places waiting for delivery of the apparatus from the makers. In a few instances old and out of date winding engines are being replaced by modern steam or electrically-driven plant, and there are one or two cases where the old vertical type of winding engine is in use, which were unsuccessfully sought to be exempted, which are still under the serious consideration of the colliery engineer. Detaching hooks are fitted at all the shafts where men are regularly wound, with some two or three exceptions where the headgears are being reconstructed. With few exceptions nearly all the lamps now in use comply with the Safety Lamp Order. There are large numbers with only four poles, and these so arranged that a straight line touching the exterior part of adjacent poles touches the glass. Although a reason- able time is allowed for this matter to be altered, the lamps are now being dealt with in batches, so that by January 1916 all should be in order. Approved glasses have been obtained, and generally the safety lamp question has been satisfactorily dealt with throughout the division, though in many cases there was apparently a failure to understand the meaning of the Order. There is an increase of 1,567 in the number of electric safety lamps in use. With regard to management, the provisions of the Act have necessitated an increase in the number of managers and under-managers. In some cases where one manager had charge of a group of mines separate appointments have been made, and the former manager has been retained as agent. At a few mines in the division examiners have been appointed with duties similar to those of deputies in other parts of the country—that is, to inspect the districts and supervise, and not to do the timbering. It has been necessary in a few cases to draw attention to the size of the deputies’ districts, and in each case more men have been appointed to do the work. In the county of Durham a deputy has charge of from eight up to 30 getters, while in Northumberland the average for each deputy is only 13. The examinations for fire- men’s, &c., certificates have been conducted in accordance with the conditions laid down by the Home Office. The numbers of candidates who have obtained certificates up to the end of 1913 was 18,469, there being 983 failures. In probably no other coalfield is the power given to the workmen, under section 16 of the Act. so much taken advantage of as in Durham and Northumberland. At a great number of the collieries in these two counties the workmen’s inspectors make a complete inspection of the mine every three months. It is the custom for the local inspectors to be appointed for 12 months, and in addition to making the quarterly inspection the two workmen always visit the scene of a fatal accident. The same system applies, but in a lesser degree, to Cumber- land and Cleveland. The inspectors draw attention to everything which they consider should be improved, whether or no it happens to be a breach of the Act, and their reports have quite a distinct value of their own. The requirements regarding ventilation plans and prescribed form of report books are well observed, but the reports in the latter are not as full and complete as they should be. The question of ventilation is a very serious one at some of the old mines, both in Durham and Northum- berland. The working faces have advanced so far from the shafts, and the return airways have apparently been neglected, so that the temperature at the working faces is higher than it should be, and any temporary derange- ment in the ventilation causes the workings to become foul. Such places are being frequently inspected, and suggestions made respecting increasing the number of splits and enlarging the airways, so that it is hoped the conditions will soon materially improve. The provisions of the Act have necessitated sinking a new shaft at one mine, and erecting new fans at several mines. The requirements as to measuring the air current have proved to the management in many cases how little air there is to measure. There may be an excellent current of air travelling on the main engine plane, but poor stoppings and an indifferent main return will not ensure it reaching where it is most required. The inspection staff are continuing to take samples of air for various purposes, and up to the end of the year 888 had been taken and analysed. There are many mines in this division, particularly in Northumberland, where safety lamps are used only by officials. Fortunately inflammable gas is seldom seen, so the miner continues to use a candle, and it would be difficult at many places to persuade him to adopt any other form of lighting. At six mines, how- ever, during the year small quantities of gas were ignited which caused injuries to persons in each case and necessitated the adoption of safety lamps. Wherever safety lamps are required by the Act or the Regulations a uniform system for searching persons employed below ground has been adopted. That searching is necessary is conclusively proved by the number of persons found with prohibited articles in their possession. The class of mine makes little difference in this respect, as matches are discovered in the most gassy mines equally with those which are not so dangerous. It would materially reduce the risk of these forbidden articles being taken into the mine if each person were allowed to deposit his smoking equip- ment in the lamp room upon the number represented by his safety lamp. One of the new provisions in the Act under section 36 is apt to be lost sight of. Officials have not always realised that “ every part of a mine in which 10 or more persons are employed at the same time shall be provided with at least two ways affording means of egress to the surface.” While on the whole the provisions of the section are being carried out, in two or three cases attention has had, to be drawn to the fact that there was only one road into a small district. Part of section 40 has already been referred to with reference to the provision of guides. In most cases these were already in accordance with the subsection, but one or two instances occurred in which there was a misapprehension as to the meaning of the clause, and particularly as to the interpretation of “ working shaft ”; in other cases proper provision was not made because so much alteration and work had to be done in the shaft owing to earth movements; because pumps and haulage ropes had first to be removed; because it was for some time not decided to carry on the mine, &c. Keps have been provided where necessary. With perhaps two exceptions, wherever any other winding engine or any other machinery than the winding apparatus is fixed in a winding engine-house, substantial partitions have been erected to separate them. With regard to catches and gates, or other rigid fences, some form of protection has been applied to all the cages in this division. Much improvement has been effected since the Act came into force. In an endeavour to conform to the requirements of the Act, possibly much longer time has been taken and has been required, and much greater expenditure incurred in order to bring mines into line in connection with those sections which deal with travelling and haulage roads than with any other portion of the Act. To provide the 2 ft. of space at the side of haulage roads, required by section 43 (1), has meant in many cases very hard work under considerable difficulties. It is usually work that can be best done at week-ends; but the average miner has a strong antipathy to week- end work. Where side has not been taken off, and where such a space is difficult to obtain, as at curves, notices prohibiting persons travelling have been posted up, and also in some cases a haulage hand had been stationed at the place to prevent persons travelling. At many places special travelling roads are being made in order to keep workpeople off the haulage roads altogether. The Act provides for persons being allowed to ride on sets or trains of tubs with the written permis- sion of the manager, if they are being conveyed to or from their work. This is interpreted as allowing men to ride outbye on the tops of the full tubs. It saves making up a special train for the purpose, and does not impede the output; but the custom is fraught with considerable danger, as in all cases the persons so riding can never be very far from the roof or roof supports, and forgetfulness may at any time lead to disaster. With regard to the clear space to be provided under section 43 (3), where tubs are coupled or uncoupled, a great amount of work has had to be done, but the position in this respect is now quite satisfactory. In most cases it has been found best to make a space of 3 ft. between the tubs on sets of rails, as this allows a shorter length of roof balk to be used. There was considerable misconception regarding the width of refuge holes ; the dimensions specified in the section was taken to mean the minimum, instead of as near as may be the exact width. Many refuge holes have had to be built up, and much has yet to be done as regards size. A very good rule in this connection is in force at some mines; when each refuge hole is completed in accordance with the requirements of the section, a record is made in a book kept for the purpose. The inspector of horses and the workmen’s inspectors have on several occasions drawn attention to the dimensions of the horse roads, usually because the animal was rubbing its harness against the roof or roof supports. These matters were usually promptly attended to. Attention has had to be called in a few cases to an insufficiency of lockers, and to the lack of stop blocks at the top of inclines. The same may be said of the use of holing props or sprags; there is not in this division anything like the keenness for setting these supports which obtains in the Midland counties. One of the new provisions in the Coal Mines Act stipulates that so long as persons are in the mine below ground, a competent person shall be in constant attendance at the top of the shaft for the purpose of receiving and transmitting signals. There appears to be no disposition to evade this, but it may be as well to point out that the section does not say merely that the person shall be within hearing of the signals, but that he shall be at the top of the shaft. The same section, with the qualification about persons authorised in writing by the manager to give signals, requires an onsetter at every shaft landing, if persons in the mine may require to be raised from that landing. In some cases where there are several landings within a short distance of one another, pipes are provided connected to the main inset, so that persons can call the onsetter’s attention and intimate that they wish to leave the mine. Though the onsetter may be always in attendance when persons use the shaft, it has been pointed out that one man cannot be in constant attendance at more than one entrance into the shaft, and any other arrangement is an infringement of the A?t. The new provisions respecting steam boilers are being observed, and in some cases where boilers existed under- ground they have been removed, and electric motors installed in the place of the steam engines. The regulations made under section 57 and 86 of the Act, as to the hours of employment of winding engine men, which came into force on July 1 last, are being well observed. While at many mines an eight-hour shift is being worked, at the majority of the coal- drawing shafts the shift during which the heavy coal winding is in operation has been reduced. At a very large number of places the length of shifts are seven, eight and nine hours respectively.
