摘要
煤矿井下积水会增加井下气体浓度,影响井下作业安全,防治水可以及时排除井下积水,保障井下作业人员的生命安全.主要利用定向钻探技术,探查煤矿内老空积水现象、探测煤炭作业面底板承压、顶板水的探测技术、定向探水钻孔、开展注水耐压试验,保证煤矿防治水作业更顺畅,保障了井下安全生产和地面地下水环境的安全.
Abstract
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.
