1298 THE COLLIERY GUARDIAN June 28, 1918. SPRINGHILL FIREDAMP EXPLOSION. Inspector’s Report.* Mr. W. Walker, H.M. Acting Chief Inspector of Mines, has issued his report on the causes and circum- stances attending the accident which occurred at Springhill Colliery, Ayrshire, on July 18, 1917, from an explosion of firedamp, and by which four persons were killed. At the fatal accident enquiry held by the Sheriff- Substitute at the Sheriff Court, Kilmarnock, on August 17, 1917, in connection with this accident, the jury returned the following verdict: “That on July 18, 1917, the deceased, Thomas Walker, John Walker, Thomas McLean, and William Durney, while in the course of their employment in the underground workings leading from the Main coal to the Major coal seams of No. Cauldhame Pit were so severely injured by an explosion of firedamp that they died from the effects thereof in the Kilmarnock Infirmary, the said John Walker on July 18, the said Thomas Walker and Thomas McLean on July 19, and the said William Durney on July 23, 1917.” On the morning of February 5 the Inspector opened his enquiry at the Sheriff Couft, Kilmarnock, and took the evidence of the available witnesses. The owners of the colliery were represented by Mr. James M. Inglis, writer, of Kilmarnock; Mr. John Bain, writer, appeared for the relatives of the de- ceased; Mr. Robert Smillie appeared for the National Union of Scottish Mine Workers; Messrs. James Brown, James Hood, James Smith, and Alexander Campbell for the Ayrshire Miners’ Association; Mr. H. Walker, H.M. inspector of mines for the Scotland division, and Mr. F. H. Wynne, one of the senior inspectors of mines in that division, were also present Sixteen witnesses were examined. A plan and section of the stone mine and workings in the Major coal seam, which were the subject of this enquiry, are attached. The colliery was originally worked by Messrs. A. Finnie and Son, of Kilmarnock, but on its working being abandoned by them, Messrs. of the accident they descended the shaft at between 6.45 and 7 o’clock, and proceeded to the fan at the bottom of the stone drift or mine leading to the Major coal seam. The fan was then standing. Cook arrived first and started to work the fan, and Turner joined him shortly afterwards. Thomas Walker and John Walker went into the same place and were followed by William Durney and Thomas McLean, who sat down and talked with the two Walkers; they all had naked lights. When the fan had been going about half an hour they proceeded to walk up the mine. Durney went first, and the three others followed him after an interval of about five minutes. In a very short time (estimated by the fan boys to be about ten minutes) the explosion occurred. One of the boys was knocked over, there was a shower of small stones and mud, and their lights were ex- tinguished. They crawled to a ventilating door and shouted for help, and a roadsman came. Thomas McLean then came down the mine seriously injured. Thomas Walker, William Durney, and John Walker followed, all seriously injured, and were removed to the Infirmary at Kilmarnock. Subsequent examina- tion of the mine showed that nearly at the top of it there was an accumulation of inflammable gas. Lying on the roadway several open lamps were found, several caps, some tools, and a pick and shovel. The first lamp was 16 ft. from the top of the mine, the rhones were broken 19 ft. below where this lamp was found. There is little doubt that the naked light carried by William Durney had caused the explosion at or near the point where the lamp was found (16 ft. from the top of the mine). Some force was generated by the explosion, as the rhones were broken. In order to obtain a clear and concise idea of the circumstances which led up to and caused the acci- dent, it is necessary describe what occurred from the preceding Saturday. On this day (July 14), on account of the unsatisfactory nature of the coal, it was decided to abandon its working, and no coal get- ting was done after that date. The fireman McChristie) went in at 9.15 on Sunday night for the purpose of were three firemen for the district in which the ex- plosion occurred, viz., William Durney, Robert McChristie, and James Bowie. Durney was the day fireman, James Bowie was on the afternoon shift, and Robert McChristie on the night shift, and as they were always employed on the same shifts, Durney made the inspection and report required by section 64 (1) of the Coal Mines Act before the day shift started work during the week, and on Sunday night Robert McChristie made an inspection under this section before the night shift started work. The staffing of the mine appears to have been sufficient to comply with the requirements of the Coal Mines Act and secure safety, but the inspector regrets he is unable to report that the management carried out the duties placed on them by the Act in a satisfactory manner. The hand fan at the bottom of the stone mine was always stopped on Saturday afternoon, usually between 1 and 2 o’clock, and did not start again until some time on Sunday afternoon, depend- ing when the shift of men were coming in on Sunday night, and during that period there was no means of ventilating the stone mine and workings in Major coal seam, and firedamp naturally accumulated. Two of the firemen were brought in earlier on Sundays to start the fan and remove the accumulated firedamp, and both the firemen (McChristie and Bowie) stated in their evidence that it never took less than four hours to do so. From the evidence given at the enquiry the inspector is of opinion that breaches of section 29 (1) of the Coal Mines Act, 1911, were committed by the owners, the manager (Mr. Baillie) prior to July 14, and Mr. Robert Nelson, who acted as manager after that date, by reason of their failure to produce constantly an adequate amount of ventilation to dilute and render harmless inflammable and noxious gases in the stone mine and Major coal seam workings, owing to the fan, which was the only means of providing ventilation of that seam, being allowed to be stopped every Saturday afternoon from between 1 and 2 o’clock to the following Sunday afternoon, and also 5 a 3 § ECTION.. a.b. c I <0 o o Q) I e o I PLAN & SECTION SHEWING STONE MINE FROM MAJN TO MAJOR COAL WHERE IGNITION OF FIREDAMP HAPPENED ON WEDNESDAY THE 18™JULY 1917 CAUSING THE DEATH CF WILLIAM DURNEY, THOMA^ WALKER,JOHN WALKER & THOMAS M9LEAN. J. and R. Howie Limited, the present owners, obtained possession of the mine and have since worked it. An area of Major coal seam was shown on the plan as being unworked, and they decided to prove the coal in this area. For this purpose a stone mine or drift was driven from the Main coal seam, which it overlies at a distance of 66 ft. The mine was started some time prior to November 1916; it was driven at an inclination of about 1 in 4|, and cut the Major coal seam at a distance of 185 ft. from the workings in the Main coal seam. As the quality of coal was doubtful, only one roadway was driven to it for exploration purposes. When the drift reached the Major coal seam, it was found the coal was dipping at 1 in 20 in the opposite direction to the stone mine or drift. Naked lights were used by all the workmen and also by the firemen, except when they were making the examinations required by sections 64 and 65 of the Coal Mines Act. Ventilation was obtained by a hand- driven Sirocco fan, 10 in. in diameter, placed at the foot of the drift; air was forced up through a range of wooden pipes or rhones, said by the late manager, Mr. D. Baillie, to be 12 in. by 12 in. At the top of tiie mine a level was driven a distance of 40 ft. to the left, known as Anderson’s place, and another to the right, a distance of 95 ft., known as McCrindle’s place; and out of the latter another place was driven to the right or rise, a distance of 40 ft., known as Hunter’s place. McCrindle’s place was ventilated by means of a second fan, also driven by hand. This second fan had no connection with the accident which occurred on July 18 last, and is therefore not shown on the plan and section. The explosion occurred at about 7.30 a.m. on Wednesday, July 18, and four men, including the fireman, William Durney, were so seriously injured that they died at Kilmarnock Infirmary later. The evidence of the boys employed at the fan (Archibald Cook and John Turner) showed that on the morning *Cd. 9053. making his examination, but the fan at the foot of the stone mine had not started at that time, and he found what he described as blackdamp and gas at the top of the stone mine. The fan appears to have been kept going during Monday morning shift, although no one was working in the Major seam, but the gas was not cleared out, for the day fireman (William Durney) reported its presence in the two reports of his inspections during his shift on that day. On Tuesday morning two men, Thomas and John Walker, were employed in removing rails and the small fan from the Major coal seam workings; the fan at the bottom of the mine was kept going during the time they were doing this work. The two boys who in the ordinary course of working should have gone to the fan at 10 o’clock on that night were John Weeks and John Durney. The former come to the pit but returned home, and the latter did not come at all on the night shift, but came on the following morning and started work as a drawer, by directions of Mr. Nelson, in another part of the mine. The rails were not all removed on the Tuesday; those in the stone drift up to where the explosion occurred were to be removed, and the two Walkers and McLean were at the time of the explosion proceeding up the drift to complete this work. The report for the day shift on Monday was the last report of an inspection of the Major coal workings and the drift which appears in the report books. The two firemen, James Bowie (afternoon shift) and Robert McChristie (night shift) made their last inspections on Friday, July 13, and Monday, July 16 respectively, and they explained at the enquiry that they did not make any on the following days because the workings were stopped and no one was in the Major coal seam or the drift leading to it during their shifts after these dates. Up to July 13 last Mr. D. Baillie was manager of the mine. He was succeeded by Mr. Nelson as temporary manager, and Mr. John Banks was appointed under-manager on May 8, 1917, and they were so acting on the date of the accident. There for at least 16 hours before the accident. As a result of this failure gas accumulated to such an extent that it never took less than four hours to remove it, and the roads and workings were not in a fit state for working or passing therein. This practice was the cause of the accumulation of firedamp which resulted in the explosion. Further, the system of ventilation on the date of the explosion and for some time pre- viously (for how long none of the witnesses were able to say) was unsatisfactory. • A brattice sheet had previously been fixed across the road, on the inbye side of the fan, to prevent the gases coming down the stone mine into the return airway from passing the inlet to the fan and mixing with the pure air forced by the fan up the wooden pipes or rhones to the workings in the Major coal seam, but this brattice had been for some time previously displaced or re- moved, with the result that the foul gases brought down the stone mine or drift by the fan mixed with the fresh air at the inlet to the fan, and part, at least, of them were driven back up the mine and into the workings. Such a system was clearly inadequate. On the evidence Mr. Walker can come to no other conclusion than that both the managers (Messrs. Baillie and Nelson) were guilty of gross mismanage- ment. They saw and signed the firemen’s reports, which showed that the presence of gas was being fre- quently reported—between March 12, 1917, and the date of the accident there were no less than 33 separate reports by the firemen of gas being found in the stone mine and Major coal seam—but no enquiry into this serious condition was made, and steps were not taken by them to provide and maintain a constant and adequate amount of ventilation. If they had carried out their duties as an ordinarily careful manager would have done, the gas would not have accumulated and the accident would have been pre- vented. They both admitted in evidence at the en- quiry that the fan was stopped, from Saturday after- noon to Sunday afternoon each week, with their knowledge and consent, and that they knew gas
