一、地质采矿条件魏寨村位于平顶山十矿井田西翼戊组二采区123、125两采面上方。该地区地表平坦,地质条件简单,煤层赋存稳定,煤层倾角为9度。上覆岩层为二迭纪页岩,砂岩及砂页岩互层。冲积层为第四纪粘土层,厚约50至90米。采煤方法为倾斜长壁后退式,全陷管理顶板,其采矿条件如表1所示。由于采区倾斜长度较小,因此魏寨村的房屋全都遭受非充分采动的影响。
I. Geological Mining Conditions Wei Zhaicun is located at the top of 123,125 coal mining areas in the second sector of the Second P Group in West Mine of Pingdingshan Ten Mine Field. The surface of the area is flat, with simple geological conditions and stable coal seam. The coal seam dip angle is 9 degrees. The overburden is Permian shale, sandstone and sand shale interbedded. Alluvial layers of Quaternary clay, about 50 to 90 meters thick. Coal mining methods for long-term tilt back type, all-sink management roof, the mining conditions shown in Table 1. Due to the smaller slope length of the mining area, all the houses in Weizha Village were affected by the incomplete mining.
