鹤壁六矿含煤地层为二迭系山西组,可采煤层一层(一煤)。煤层厚度5.4~11.5米,平均厚度8.0米。煤层倾角一般为17°~30°,局部达50°。煤层稳定。煤层直接顶板为黑色页岩或砂质页岩,厚0.5~10.0米;老顶为砂岩,厚10~36米。煤层底板为页岩与砂岩互层。煤质牌号为瘦煤1号。自1970年9月起,开始出现了煤和瓦斯突出(以下简称突出),冲击地压,钻孔喷孔
Hebi six coal-bearing strata of the Permian Shanxi group, a coal seam can be a layer (a coal). Seam thickness 5.4 ~ 11.5 meters, the average thickness of 8.0 meters. Coal seam angle is generally 17 ° ~ 30 °, the local up to 50 °. Seam stability. The direct roof of the coal seam is black shale or sandy shale with a thickness of 0.5-10.0 m. The top of the coal seam is sandstone with a thickness of 10-36 m. The coal seam floor is interbedded shale and sandstone. Coal grade lean coal No. 1. Since September 1970, there have been coal and gas outburst (hereinafter referred to as prominent), rock burst, drilling holes
