摘要
针对矿井老空水往往具有涌水量大、破坏性强的特点,为有效治理矿井老空水,以山西某矿12#煤层8637回收煤柱工作面采煤工况与水文地质工况为例,分析了其存在的主要老空区积水情况,通过布设探放水钻孔,应用疏放水管路把积水疏放至8613采空区,经大力疏放,8611采空区积水排放了约8.1万m3,8637工作面面临的老空水安全隐患得到了排除,更好的保障了8637工作面的安全生产,该研究可为类似工况下的矿井老空水治理提供参考。
In response to the characteristics of large water inflow and strong destructive power of mine goaf water,in order to effectively control mine goaf water,taking the coal mining and hydrogeological conditions of the 8637 recovery coal pillar working face in the 12#coal seam of a certain mine in Shanxi as an example,the main water accumulation in the goaf was analyzed.Through the installation of exploratory water drill-ing holes and the application of drainage pipelines,the water accumulation was drained to the 8613 goaf,and then vigorously drained.The accumu-lated water in the 8611 goaf discharged about 81000 cubic meters,and the safety hazards of the old goaf water faced by the 8637 working face have been eliminated,better ensuring the safety production of the 8637 working face.This study can provide reference for the treatment of old goaf water in mines under similar working conditions.
