中文摘要：

针对远距离松软低渗煤层群开采问题,提出基于保护层卸压的井上下立体化煤与煤层气协调开发模式及煤层气抽采工程的布设原则。通过潘一东矿1252（1）工作面的工程实践,采用数值计算和现场实测的方法,研究了11-2煤保护层卸压开采的应力变化规律和卸压范围,评价了煤层气卸压抽采效果。实践证明,该模式的应用有效解决了工艺接续和煤与煤层气两种资源安全、高效开发的问题。

英文摘要：

In order to sotving the mining problem of soft, large distance and low permeability coal seams, the harmonic development model of coal and coal-bed metane on ground and underground with protective layer depressurized mining and project lay out principle of coal-bed metane extracted were put forward. According project practical of 1252 （ 1 ） working face in Panyidong coal mine, stresses change law and unloading scope of depressurize mining in 11-2 coal protective layer were studied by numerical simulation and filed practical, then coal bed metane extraction effect was evaluated. The practical showed that process connection and safety and high effi- cient development problems of coal and coal bed metane were solved successfully.
