中马村煤矿位于焦作矿区东部,设计年产60万吨。井田走向长9.7公里,平均倾斜长1.5公里,单斜构造。均为高角度正断层。煤层薄厚不均,有大面积的无煤区,采二迭纪大煤,厚0～13.5米,一般厚3～6米。倾角8～14°倾向东南,埋藏深度200～600米。竖井开拓,目前为单翼开采,混合式通风,矿井相对瓦斯涌出量为25～40米~3/吨,是煤与瓦斯突出矿井,从1968年至今共发生煤与瓦斯突出20次,最大突出强度650吨/次,沼气11万米~3,百万吨突出率5.2次,万米掘进突出率4.2次。
Zhongmacun Coal Mine is located in the east of Jiaozuo Mining Area, with an annual output of 600,000 tons. Minefield 9.7 km long walk, the average length of 1.5 km inclined, monocline structure. All are high-angle normal faults. Thick and uneven coal seam, with a large area of coal-free, mining two large coal, thick 0 ~ 13.5 meters, generally 3 to 6 meters thick. Inclination 8 ~ 14 ° southeast, burial depth 200 ~ 600 meters. The shaft is open up. Currently it is single-wing mining and mixed ventilation. The relative gas emission from the mine is 25 ~ 40m ~ 3 / t, coal and gas outburst mines. Coal and gas outburst occurred 20 times since 1968, Outstanding intensity of 650 tons / time, biogas 110,000 ~ 3, million tons outstanding rate of 5.2 times, million meters prominence rate of 4.2 times.
