地质概况青峰煤矿四号井地处石门县陈家湾矿区北部,为北—北东倾向单斜煤层,倾角12°～20°。煤层底板为石碳—泥盆系厚层状中—细粒石英砂岩,裂隙发育,导水性好,厚度不详。顶板为二迭系灰岩,总厚度260m以上,溶洞发育。矿井内东西各有一条走向为东—西向的大断层,为矿井采区分界线。断层描述及揭露情况胡家窑断层位于青峰煤矿四号井东翼,为该矿井一、三采区分界线,由于受东—西向力的影响,该断层
Geological Survey Qingfeng Mine No. 4 well is located in Shimen County Chenjiawan north of mining, North - North East inclined monocline, dip 12 ° ~ 20 °. The coal seam floor is a carbonaceous-Devonian thick-bedded medium-fine quartz sandstone with developed fissures and good water conductivity. The thickness is unknown. The top plate is two superimposed limestone, the total thickness of 260m or more, cave development. There is a large east-west fault in each of the things in the mine, which is the dividing line for the mining area. Fault Description and Exposures The Hujiayao fault is located in the east wing of No.4 well in Qingfeng Coal Mine and is the demarcation line between the first and third mining areas. Due to the east-west direction, the fault
