摘要
岩溶陷落柱是我国北方石炭二叠纪煤田重要的水患因素,传统的防治方法有以留设防隔水煤柱为主的预防措施和以截流注浆为主的治理措施两大类,都需要超前进行,对于巷道掘进过程中才揭露的陷落柱或者实际揭露陷落柱与前期勘探成果差异较大,影响工作面回采的,不可避免的要影响到煤矿的正常生产衔接。针对近年来采掘活动刚延深至石炭系煤层,对陷落柱治理工作开展较少,经验相对缺乏的大同煤田,结合工程实例,探讨煤矿井下陷落柱快速精准治理技术,以期为该区陷落柱水害的防治提供新思路。
Karst subsided column is an important factor of water hazard in North China Permo-Carboniferous coalfields.Traditional control methods have mainly water barrier leaving preventive measures and mainly water closure grouting governance measures two kinds,all need operated in advance.To roadway driving process revealed subsided column or practically revealed column is largely different from previous exploration results and impacted working face winning,unavoidably impacted coalmine normal production interlinks.The paper considering that the mining work only just deepening into Carboniferous coal seam in recent years,fewer subsided column governance works have been carried out.To relatively inexperienced Datong coalfield,combined with project cases,discussed coalmine underground subsided column fast and accurate governance technology;hope to provide new idea for subsided column water hazard control.
