| Abstract: | Due to the development of water-bearing sandstone in roof in the north second mining area of Xiaoqing Coal Mine,it caused a hidden danger to safety production.In order to ensure the safety of mine production,the waterrich properties of water-bearing sandstone in roof of 4 coal beds were analyzed by studying the factors such as roof sandstone deposition,lithology and geological structure.This study has certain reference value for other mine water hazard prevention work under similar conditions. |
