Research on Directional Drilling Technology in Coal Mine Water Prevention and Control Operations
Water accumulation in coal mines can increase the concentration of underground gases,affecting the safety of underground operations.Water prevention and control can timely eliminate underground water accumulation and ensure the safety of underground workers.The main use of directional drilling technology is to explore the phenomenon of water accumulation in old coal mines,detect the pressure on the bottom plate and top plate of coal working faces,conduct directional water exploration drilling,and carry out water injection pressure resistance tests to ensure smoother water prevention and control operations in coal mines,and guarantee the safety of underground production and surface groundwater environment.
