APPLICATION OF DRILLING TECHNOLOGY IN WATER PREVENTION AND CONTROL IN A COAL MINE UNDERGROUND
Coal mining is influenced by factors such as mining environment and terrain structure.Among them,water damage is a common problem that can lead to difficulties in carrying out mining work in the later stage.In this paper,the application of drilling technology in preventing and controlling water in coal mines underground was analyzedto achieve high-quality construction of coal mine water prevention and control,with the support of advanced scientific drilling technology.At the same time,the types of water hazards in coal mines should be comprehensively considered,and multiple drilling techniques such as full seam drilling with spiral drill rods and high angle upward boreholes should be reasonably applied to successfully achieve the goal of water prevention and control in coal mines.
