摘要

针对山西华阳集团新能股份有限公司二矿97307工作面瓦斯含量高、治理效果不佳的问题，进行瓦斯综合治理技术研究，在矿井原Y型通风系统基础上，采用调压减漏和封堵封漏方式降低采空区漏风量，并采用钻孔抽排方式进行瓦斯预抽排，避免采空区瓦斯从挡矸墙缝隙扩散至留巷段，降低了煤层瓦斯含量，通过瓦斯抽采量和风排瓦斯量监测，瓦斯抽采率为58.6%，瓦斯综合治理措施明显有效。
Abstract

Aiming at the problem of high gas content and poor control effect in No. 97307 Face of No.2 Coal Mine of Shanxi Huayang Group Xinneng Co., Ltd., the comprehensive gas control technology is studied. On the basis of the original Y-type ventilation system of the mine, the air leakage volume in the goaf is reduced by pressure regulating and sealing, and the gas pre-drainage is carried out by drilling and drainage, so as to avoid the gas in the goaf from the gap of the retaining wall to the retaining section and reduce the gas content in the coal seam. Through the monitoring of gas drainage volume and air drainage volume, the gas drainage rate is 58.6 %, and the comprehensive gas control measures are obviously effective.
