地质综合探测技术在顾桥矿的应用

Application of Geology Complex Exploration Technique in Guqiao Colliery

顾桥矿南翼"地质异常带"为较复杂的大型地堑构造带,断层大部分为张性正断层,上通松散层,下到1煤层底板灰岩强含水层,岩体松散破碎,胶结程度差,裂隙发育,稳定性低,部分崩解程度高。为保证巷道安全掘进,通过井下超前综合物探探测并结合钻探的方法,查清了区内水文地质、瓦斯地质、工程地质情况,做到了安全和生产两不误。

＂Geology Abnormal Zone＂ in south of Guqiao Colliery is large--scale compound graben structural zone, most of fault is opening normal fault, from soft bed to 1 coal seam floor limestone water--bearing bed, its characteristics are of soft and broken rock mass , had cementing level, crack development, low stability and high bursting level. To ensure roadway to drive safely, the authors have introduced a way of combining underground advance integrated exploration with probe boring to make a thorough investigation of geohydrology, gas geology and engineering geology in the area, which achieves safety and production.
