摘　　要：以分析煤矿深部煤层地应力分布特征以及地应力与瓦斯赋存的关系为目的,结合A煤矿工程案例,通过水力压裂法和应力解除法进行测量,系统分析研究区700~1 200 m深度范围内的垂直应力与水平应力分布,详细分析地应力与瓦斯赋存的关系。结果表明,深部煤层瓦斯赋存与地应力分布密切相关,为深部煤矿瓦斯治理提供了理论基础。In order to analyze the distribution characteristics of ground stress in deep coal seam of the coal mine and the relationship between ground stress and gas occurrence,combined with the engineering case of A Coal Mine,the vertical stress and horizontal stress distribution in the depth range of 700-1200 m in the research area were systematically analyzed by hydraulic fracturing method and stress relief method,and the relationship between ground stress and gas occurrence was analyzed in detail.The results showed that the occurrence of gas in deep coal seam was closely related to the distribution of ground stress,which provided a theoretical basis for gas control in deep coal mine.
