大同矿务局白洞矿,是由新白洞矿,和1960年5月9日由于煤尘爆炸而封闭,后于1977年恢复后的原老白洞合并而成,位于口泉沟,西、西南与四老沟矿交界,北、东北与同家梁矿交界,东南为露头线;井田走向为西北——东南,长3575m,倾斜西南——东北,长2553m,面积9.5km~2,可采煤层共7层,其中:4号、7号、8号层仅在井田北部局部赋存,已采完,15号层尚未开采;现正开采11号层、12号层、14号层。矿井沼气等级为低沼气矿井,81年鉴定的相对涌出量:CH_4为0.28m~3/t,CO_2为14.46m~3/t,煤尘爆炸指数33.1%。
Datong Mining Bureau White hole mine, is the new white hole mine, and May 9, 1960 due to coal dust explosion and closure, after the restoration of the old white hole in 1977 after the merger, located in the mouth of Quikou, West , The junction of the southwest and the Siou Gou mine, the junction of north and northeast with the same Jia Liang mine, the southeastern outcrop line; minefield to the northwest - southeast, 3575m long, slanted southwest - northeast, 2553m long, an area of 9.5km ~ 2, There are 7 layers of recoverable coal seams, of which, No. 4, No. 7 and No. 8 layers are only partially found in the northern part of the minefield, and have been taken and No. 15 has not been mined yet; and No. 11, No. 12 and No. 14 Floor. The biogas grade of mine is low biogas mine. The relative emissivity identified in 81 years: CH4 is 0.28m3 / t, CO2 is 14.46m3 / t and coal dust explosion index is 33.1%.
