采空区一直是矿山的定时炸弹,不仅严重威胁矿区的安全生产,而且对矿区或者附近的地面建筑造成极大的危害。EH4电导率成像系统由于其设备轻,速度快,精度高,探测深度大等特点,在地质勘探中得到了广泛的应用。通过EH4电导率成像系统在内蒙古宝丰煤矿区的应用实例,证明了它在煤矿采空区勘查中的良好效果。
The goaf has been a time bomb of the mine, which not only seriously threatens the safe production of the mine area, but also causes great harm to the mining area or the nearby ground construction. EH4 conductivity imaging system has been widely used in geological exploration because of its light weight, high speed, high precision and large detection depth. Through the application example of EH4 conductivity imaging system in Baofeng coal mine in Inner Mongolia, it proves its good effect in prospecting of coal mined-out area.
