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。
Fushimu mine coal and gas outburst mine, gas disaster control to reduce the gas content of coal seams, the previous application of large-diameter drilling technology to achieve poor results, slow tunneling, in order to solve this problem, the use of advanced Progressive gas drainage technology of this coal seam in gas drainage effectively reduces the amount of gas emission during excavation and greatly improves the comprehensive tunneling speed of the outburst coal seam. The relevant parameters during the excavation before and after using progressive gas drainage technology are contrasted and studied.
