整合煤矿老空区积水特征及治理
|
摘要
为解除老空区积水对整合矿井煤层再开采带来的巨大隐患,采用理论分析和现场实测方法对老空区积水来源、治理原则和方案进行研究。结果表明;两种因素作用下形成了南河煤业3#煤层老空区积水,进而提出老空积水治理的三个原则和四种方案,认为下组煤层施工钻孔疏放上组煤层积水方法较合理。提出并实施了老空区积水治理的钻孔布置参数和安全技术措施,现场实测发现有效疏排采空区积水30 000m3,老空积区水得到较好疏放。
In order to remove the hidden risks caused by old goaf water during the re-mining in integrated coal seams,theoretical analysis and on-site measurement were used to study the old goal water sources and water control principles and schemes.The results show that factors influence the old goaf water in the No.3 coal seam of Nanhe Coal Industry.Three principles and four schemes were proposed.Among them,the reasonable one is the drilling method in the lower group coal seams to drain the water in the upper group.Finally,layout parameters of the drilling holes and safety measures were proposed and implemented to control water.The on-site measurement found that the 30 000 m3 goaf water was drained effectively.
