Roof Water Damage Prediction and Evaluation of Sand‐Mud Sedimentary Tectonic Strata

Geofluids, Volume 2023, Issue 1, 2023., 2023
The prediction and control of roof water disaster has been one of the key problems in the mining process of coal resources. With the increase of mining depth in the western mining area, the roof caving and communicating to the overlying water‐bearing strata have led to an increasing number of roof water inrush accidents and deterioration of production ...
