1146 THE COLLIERY GUARDIAN. December 3, 1915. great violence, leaving a jagged aperture 9 in. to 12 in. wide along the roof and down the left side. The block was 4 ft. thick, and behind the block a space 7 ft. wide extended to a fault with a drop of ft. This space was filled with disintegrated coal of a sooty appearance. No gas was found before or after the outburst. From this fact it would appear that an isolated reservoir of gas had accumulated in the coal shattered by the fault movement. It was not in communication with a blower, and the gas was quite exhausted by the single eruption. Gas from Squeezes. The subsidence of an undermined area in a coal mine, known as a squeeze, is attended by the emission of an increased amount of gas, the volume in some instances being large. The emission is caused partly by the crushing of coal in the pillars, so that the gas that comes from them gradually under normal conditions is freed quickly. The roof is cracked to some extent, and ventilation is usually cut off, at least along some of the main airways. In the squeeze at the Stevens mine, near Pittston, Pennsylvania, in July 1904, a large volume of gas was liberated from workings in the Marcy and Red Ash beds. The air current of 120,000 cu. ft. a minute brought so much gas from the squeeze that the return air would flame in a safety lamp set near the fan in the upcast a mile distant. This condition continued for four weeks, while the operators were trying to arrest the squeeze. A squeeze at the Warrior Run mine, near Wilkes- Barre, Pennsylvania, in August 1906, was in beds E, F, D, C, and Y, under an area of 40 acres. The affected area was in the north basin, which extends from the anticline down to the bottom of the workings. In the crest of the anticline there was 350 ft. of rock cover, but the volume of gas was so great that it came to the surface, and at one place caused a serious explosion. (To be continued.)
