区段上行式开采采空区瓦斯影响分析及对策

Analysis and Countermeasures of Section Upward Mining Goaf Gas Impact

通过分析区段上行式开采采空区瓦斯涌出对矿井生产的影响,提出区段上行式开采的瓦斯治理措施,为开采缓倾斜煤层的中小型矿井生产规划和技术方案决策提供科学的理论依据。实践证明,该抽采方法对采用区段上行式开采的矿井具有一定的实用性,值得推广应用。

Through section upward mining goal gas emission of coal mine production is analyzed, the influence of section of ascending mining gas control measures are proposed, for small and medium- sized coal mine production of flat coal seam mining planning and technical scheme decision-making to provide scientific theory basis. Practice has proved that the extraction method of using extent upward mining mine is practical, is worth popularization and annlication.
