Research on the Influencing Factors and Prevention Techniques of Water Inrush from Coal Mine Floor
During the coal mining process,water inrush occurs from time to time,which seriously endangers the safety production of coal mining enterprises.Taking Pingkou Coal Mine in Shanxi Province as an example,the height of the water conducting failure zone of the coal seam floor was calculated based on on-site drilling observation data and empirical formulas.The main factors affecting water inrush from the coal seam floor,such as formation pressure,geological structure,mining parameters,and aquifer pressure,were analyzed.Technical measures such as coal seam floor grouting and coal mining method optimization were adopted to improve the safety of aquifer coal mining and effectively reduce the possibility of water inrush from the coal seam floor.
