一、井田水文地质条件本井田主要勘探对象是伊敏组(K1y)含煤地层,煤层位于浸蚀基准面以下,地表无露头,可采煤层距地表最浅处88米,区内构造简单,地层近水平状产出,地层倾角一般1°～4°。通过勘探区内九个水文地质孔的勘察结果,矿床充水主要以孔隙含水层充水为主,充水方式为煤层顶、底板间接充水,水文地质
I. Field Hydrogeological Conditions The main exploration target of this field is the coal bearing formation of the Yimin Formation (K1y). The coal seam is below the erosion datum and the surface is free from outcrops. The recoverable coal seam is 88 meters from the shallowest surface of the earth’s surface and the structure in the area is simple , Strata output nearly horizontal, stratum dip generally 1 ° ~ 4 °. Through the investigation results of nine hydrogeological holes in the exploration area, the waterflooding of the deposit is mainly dominated by the aquifer of pore aquifer, and the water filling method is the top of the coal seam, the floor is indirectly filled with water, the hydrogeology
