摘要
A矿井煤层厚度及顶底板变化幅度较大,同时煤层瓦斯含量高,底板有突水危险。结合该矿井底板承压水巷道掘进施工,利用钻探和物探相结合的超前探测手段掌握该矿井的地质情况,以保障掘进巷道施工安全,防止瓦斯事故和水害事故的发生。
The thickness of the coal seam and the variation of the roof and floor in A Mine are large,meanwhile the coal seam gas content is high,and the floor is of water inrush danger.Combined with the tunneling of the floor confined water roadway in the mine,the geology of the mine was mastered by the combination of drilling and geophysical exploration,to ensure the safety of the roadway excavation construction and prevent gas accidents and water disasters.
