掘进巷道超前探测技术研究

Research on advanced detection technology in tunnel excavation

根据《煤矿防治水规定》要求,矿井巷道在掘进前,应当采用物探、钻探、巷探和化探等方法对掘进前方一定范围内的导含水构造进行探测,以查清探测范围内的水文地质情况.以邢东矿为例,提出一套井下直流电法超前探测配合巷道底板超前钻探探查巷道前方及底板的导含水构造的综合技术,以确保巷道在掘进过程中的安全施工,防止出水事故的发生.

According to the Regulation of the Mine Water Prevention and Control, geophysical prospecting, drilling, lane and geochemical exploration methods are used to detect conducting and water - bearing structure before tunnel excavation. The paper proposes a set of technology to exploratory conducting and water- bearing structure by direct current method of advanced detection and floor advanced drilling and by taking Xingdong mine as a case study, in order to ensure construction safety in tunnel excavation and to prevent water inrush accidents.
