摘要
煤矿井下巷道掘进容易对地下水系统造成破坏,云岗矿12-2#层410盘区21003巷坚持"有掘必探、先探后掘"的原则。本文对21003巷有掘必探设计方案进行了详细的研究,并制定了相应的安全技术措施,消除了21003巷安全隐患,保障了井下的安全生产。
Underground roadway excavation in coal mine is easy to cause damage to groundwater system. 21003 roadway in 410 panel of 12-2 stratum in Yungang Mine adheres to the principle of "excavation must be explored before excavation". This paper makes a detailed study of the design scheme of roadway 21003, and formulates corresponding safety technical measures, eliminating the hidden dangers of roadway 21003 and ensuring the safe production of underground.
