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 ...

Deep Underground Science and Engineering, Volume 1, Issue 2, Page 148-164, December 2022., 2022 We conducted a new approach of mine water‐deep geological storage, the results showed that the hydrogeological feasibility of Baotashan coarse sandstone (BCS) was impressive and useful for real project. The effective porosity of BCS aquifers ranged from 1.36% to 3.46% and the capacity of mine water geological storage was 0.455–1.266 Mm3 for 1 km2 in ...
