在淮北地区承压水上开采煤层的经验基础上 ,结合刘桥二矿实际 ,设计刘桥二矿以 61 1 2、61 1 3、652工作面为代表的高承压水上初步试验开采。通过对试验开采的实践总结 ,对承压水上安全开采煤层的可行性进行了有益探索 ,对承压水上开采煤层时 ,底板涌水形式及其实质进行了深刻分析 ,试验开采经验对其它矿区类似条件下的承压水上开采具有现实的借鉴意义。
Based on the experience of coal mining on confined water in Huaibei area and the actual situation of Liuqiao No.2 coal mine, the preliminary trial mining of high confined water, represented by 61 1, 261, 13652 faces, was designed. Through the practical summary of experimental mining, this paper makes a useful exploration on the feasibility of confined water-safe mining of coal seam. The author analyzes the form and essence of gushing water of bottom floor when coal seam is confined by water pressure. Under confined water mining has practical significance.
