引黄工程北干线1号隧洞煤矿采空区勘探方法探讨

The Exploration Method of Mining Gob Near by the No.1 Tunnel of the North Main Branch of Yellow River Diversion Works

山西省万家寨引黄工程北干线1号隧洞,穿过崔家岭等煤矿采空区的状况会关系到输水隧洞的安全。经研究提出了采用瞬变电磁法钻探验证法、井下电视法、地表及深部岩石变形监测法等新技术、新方法,对煤矿采空区进行,勘探,较全面地查明了采空区的地质条件和沉降变形情况,为采空区的治理提供了依据。

The No.1 Tunnel of the north main branch of gob of Cuijialin mine.Electro-magnetic metnod,dfilling method,underground monitor and rock degformation monitor is used to explore the geological conditions and subsidence of the gob to supply references for gob control.
