摘要
随着大同煤矿集团公司实现由侏罗纪向CP纪煤层开采的转移,必须查明奥灰及CP纪地层的含水性。2003年,集团公司在白洞试验区内施工了一水文工程孔,通过抽水及注水试验,探明了C2b,C3t,P1s,J1y,O1地层的岩性、厚度、埋藏条件、富水性、涌水量等水文情况,为开采塔山井田CP纪煤层提供了可靠的水文地质资料。
With the transfer from the Jurassic period to the permo-carboniferous for the Datong Coal Mine Group Co., it is necessary to investigate the water inflow ordovician period and the CP period. The corporation drilled a testing hydrologic hole in Baidong Mine Area in 2003, verified the rock characteristics, thickness, existing condition water inflow etc. of the C2b, C3t, P1s, J1y,O1 strata by draining and pouring water experiment, and provided the reliable hydrologic data for the CP period seams mining of Tashan mine field.
