| 摘 要： | 以平煤天安五矿己15和己16=17煤层为例，对近距离煤层群瓦斯抽采技术进行了分析研究。由于己15煤层与己16,17煤层层间距较近且厚度不均，为了防止采掘施工中煤层初期来压的瓦斯突然涌入工作面，在掘进机巷过程中，从打探煤及探构造孔入手，对机巷瓦斯进行了突出预测敏感指标及临界值研究，并实施了立体抽放技术，实现了安全生产。

| Abstract: | This article take Pingdingshan Coal Co.,Ltd.Tianan five ore oneself 15 and the 16,17 coal beds as an example,pulled out to the short distance coal synusia gas picks the technology to conduct the analytical study.Because oneself 15 coal beds and oneself 16,17 coal bed level spacing and nearly thickness is uneven,to prevent in the excavation construction to put on the gas which the 16,17 coal beds and oneself 16,17 coal bed initial period press to emerge the working surface suddenly by mistake,and searches th... |
