| 摘 要： | 王坡煤矿是高瓦斯矿井,已有的井下瓦斯抽排不能满足矿井安全生产的要求,迫切需要通过地面抽采来缓解。在已有地质成果基础上,采用煤层气藏数值模拟方法,对王坡井田地面煤层气抽采工程部署方案进行优化。结果表明:A区块是井田煤层气开发试验首选区,以梅花形井网作为试验井网,井间距300m×250m,井网长轴方向60°。这种布井方式在工程实践中取得了较好效果,具有较大的推广价值。

| Abstract: | The Wangpo coalmine is a gassy mine. Existing underground gas drainage could not satisfy requirements of mine safety in production, thus surface CBM drainage is urgently needed. On the basis of available geological data, using CBM reservoir simulation method optimized surface CBM drainage engineering deployment scheme. The result has demonstrated that the block A is minefield CBM exploitation test preferred area, taking the quincunxial well pattern as the testing pattern, with well spacing 300m×250m, orientation 60°. This well pattern has been achieved good results in project practices, thus worth of spreading. |
