突出厚煤层瓦斯立体抽采技术与抽采效果分析

Three-dimensional Gas Drainage Technology for Thick Seam with Outburst Hazard and Analysis on Its Effect

煤层瓦斯抽采作为解决煤与瓦斯突出的有效手段被广泛应用于生产实践。为了探索瓦斯立体抽采技术在突出厚煤层中的适用性,通过对南山煤矿盆底区南翼15#突出危险煤层采用立体抽采钻孔布置的工艺与效果分析,总结出突出厚煤层采用立体抽采技术的条件与措施,对于类似条件的煤矿生产实践有重要的指导意义。

The gas drainage from coal seams, as an effective measure against coal and gas outburst, has been widely applied in the actual production, For probing the applicability of three- dimensional gas drainage technology in the thick seam with outburst hazard, this technology was practiced in No. 15 outburst seam on southern wing in basin bottom district of Nanshan Mine, analysis was made on the borehole arrangement and effect, and the conditions and measures for the tree-dimensional gas drainage from thick seams with outburst hazard were summarized, so this gas drainage technology is of important guiding significance for coal production of the mine with similar conditions.
