A Simple and Efficient Way to Detect the Mining Induced Water-conducting Fractured Zone in Overlying Strata

Energy Procedia, 2012
AbstractCoal mining operations in China are often threatened by the invasion of the groundwater into the mining panels. The most likely water disaster affecting the safe operation of coal mines is water from Cenozoic porous aquifers in the alluvial plain areas flooding into the mine.
