摘要
杉木树矿为煤与瓦斯突出矿井,治理瓦斯灾害以降低煤层瓦斯含量为主,以前采用的走向大直径抽采钻孔技术应用效果差,掘进速度慢,为解决此问题,使用了能提前进行瓦斯抽采的本煤层递进式瓦斯抽采技术,有效降低了掘进期间瓦斯涌出量,极大地提高了突出煤层综合掘进速度。对比研究了使用递进式瓦斯抽采技术前后掘进期间的相关参数。
Shamushu coal mine is a coal and gas outburst coal mine, the way to control gas disaster is reduce gas content in coal seam. The application effect of large diameter drilling hole technology is poor, low speed. In order to solve this problem, progressive seam gas drainage technology was used. it can effectively reduce the gas emission rate during the tunneling period, and greatly improve the tunnelling speed of outburst coal seam. Comparatively study the relevant parameters before and after using progressive gas drainage technology during tunnelling oeriod.
