摘要
泊里煤矿为典型的高瓦斯矿井,根据分析,在回采面、掘进面、采空区等位置处运输通过的风量均小于稀释瓦斯所需要的风量。按照传统的单一抽采技术方案无法满足不同采区的瓦斯抽放要求,因此根据井下实际情况确定了不同区域采用不同抽采方案的联合抽采工艺,对该联合抽采工艺要求进行了分析。应用结果表明,该技术能够有效地确保井下瓦斯抽采的可靠性,为高瓦斯矿井制定抽采方案提供了参考。
Boli Coal Mine is a typical high gas mine,and according to analysis,the air volume transported through the mining face,excavation face,goaf,and other positions is less than the air volume required to dilute gas.According to the traditional single extraction technology scheme,it cannot meet the gas drainage requirements of different mining areas.Therefore,based on the actual underground situation,a combined extraction process using different extraction schemes in different areas was determined,and the requirements for this combined extraction process were analyzed.The application results indicate that this technology can effectively ensure the reliability of underground gas extraction,providing a reference for formulating extraction plans for high gas mines.
