Comprehensive Exploration Technology of Water Disaster Prevention and Control in Coal Mining Roof

Top roof water is the direct water disaster troubling the coal mine. With the modernization of exploitation method and the increasing of exploitation, the threat of top roof water to coal mine is also increasing, damaging more and more the rock mass in coal seam roof. Therefore, it is important to study deeply into the exploration technology of top roof water disaster prevention and control. We take the NO. 3 mine shaft in Pingshuo as an example, introducing comprehensively main content and methods of exploration of coal mine top roof water, demonstrating the application of remote sensing hydro geological survey, geophysical prospecting, hydrochemistry and environment isotope, etc advanced exploration methods in coal deposits hydro-geology and "tri figure-double prediction method" of water disaster treatment.
