【摘要】 为了研究段王煤矿15号煤层瓦斯地质规律,采用了瓦斯赋存构造逐级控制理论,结合现场实测资料,研究了区域及矿井地质构造,以及煤层埋深、断层、褶皱构造等因素对瓦斯含量的影响,确定了15号煤层的瓦斯风化带,并对该煤层煤与瓦斯突出危险区进行预测,为合理开发利用煤层瓦斯,防治煤与瓦斯突出和今后的安全生产提供科学依据。更多还原

【Abstract】 In order to study the gas geology regularity at No.15 coal seam of Duan Wang Coal Mine,the gas deposit structure distinction control theory is adopted. In combination of site measured data,the influence on gas content from the regional and coal mine geologic structure,as well as factors including coal bed burying depth,fault,and fold structure are studied. As a result,the gas weathering zones of No.15 coal seam is defined and the coal and the gas prominent hazardous areas are predicted,providing a scientific basis to prevent and control coal and gas outburst and future safety production.更多还原
