一、矿井地质概况:我矿位于焦东煤田方庄井田,走向长5公里,倾斜长约1.6公里,面积8.8平方公里.矿区北靠太行山,南处山前平地,东北有季节性石门河,汛期有山洪泄流,地势比较平缓.开采煤层属石炭二迭系,上部为第四系地层所复盖,厚度一般在70米左右,煤层距地表深度70米～550米.煤层埋藏比较平稳,单斜构造,走向南西转北西,呈一扇形,倾向南东至北东,倾角15°～20°(南陡北缓),可采煤层有三
First, the mine geology Overview: Mine is located in Jiaozhuang Coalfield Jiaozhuang coalfield, to 5 kilometers long, about 1.6 kilometers long slope, an area of 8.8 square kilometers. Mining north of the Taihang Mountains, south Pingdingshan, northeastern seasonal Shimen River, Flood flood flood, the terrain is relatively flat .Mined coal is Permian 2 Diego Department, the upper part of the Quaternary strata covered, the thickness is generally about 70 meters, the coal seam depth of 70 meters to 550 meters from the surface.The coal seam burial is relatively stable, Monoclinic structure, turning to the west to the northwest, showing a fan-shaped, tend to the east and north east, dip 15 ° ~ 20 ° (south steep north slow), can be three coal seam
