摘要
本文通过对永定庄煤业有限责任公司石炭系的资料成果和实际调查的综合分析、地面和井下物探、井下超前钻探,地面探放水孔和井下探放水孔等的综合防治水技术方法,最终排除了8205工作面的同层水患和上覆采空区水患,确保了8205工作面的安全回采。
In this paper,through the comprehensive analysis on the carboniferous data and actual investigation ofYongdingzhuang Coal Industry Co.,LTD.,the floods of the same seam and overlying goaf in the8205working face areeventually ruled out by using ground and underground geophysical exploration,underground advance drilling,groundprospecting and drainage water hole,underground prospecting and drainage water hole and other comprehensiveprevention and control water technology methods,it ensures the safety mining of the8205working face.
