摘要
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 mining the coal layer above the confined water in Huaibei District and according to the fact of Liuqiao No.2 coal mine, the preliminary test mining above the high confined water at 6112 , 6113 and 652 mining work face is designed in Liuqiao No.2 coal mine. Through the conclusion of the test mining , the possibilities of mining the coal layers above the confined water is studied, the form of inrush from the floor and its essence is analyzed when the coal layera are mined on confined water.
