摘　　要：通过在工作面上下同步实施瓦斯抽采,可以实现对瓦斯的高效治理与安全控制。以A煤矿四盘区41601运输巷掘进工作面为例,应用作业面超前预测技术、水力压裂技术、采空区管路预埋技术、递进式抽采技术,形成一个立体的瓦斯抽采网络。结果表明,高位钻孔与地面钻孔上下联合的举措能够有效降低煤层间瓦斯含量和压力,有效预防安全隐患,保障作业安全。By implementing up and down synchronous gas extraction on the working face,efficient gas management and safety control can be achieved.Taking 41601 transportation roadway excavation working face in the fourth panel area of A Coal Mine as an example,a three-dimensional gas extraction network was formed by applying advanced prediction technology,hydraulic fracturing technology,pipeline pre-embedding technology in goaf,and progressive extraction technology.The results indicate that the joint measures of high-level drilling and ground drilling can effectively reduce the gas content and pressure between coal seams,prevent safety hazards,and ensure operational safety.
