中文摘要：
本文介绍了淮南矿区张北矿地面钻孔抽采采空区瓦斯技术的试验成果。运用数值模拟和现场试验的方法，分析了采空区瓦斯涌出及分布规律，优化了地面钻孔布置参数及结构的设计。在现场进行了抽采效果的考察试验，并对抽采效果进行了分析。文章对采空区瓦斯抽采技术的研究和推广应用具有一定的指导意义。
英文摘要：
Test results of surface gas extraction technology from boreholes in the goaf in Zhangbei Coal Mine, Huainan Mining Group are introduced in the paper. With the method of numerical simulation and site tests, the authors have made analysis on the law of gas emission and distribution in the goaf as well as optimized design of parameters and structure for surface borehole arrangements. Analysis on extraction results has been made based on site inspection tests. To some extent, the paper is of instructive significance for the research, promotion and application of gas extraction technology in the goaf.
