摘要

为了查明9煤层瓦斯涌出量偏高异常原因,对9煤层瓦斯涌出量预测并进行综合危险区划。结果表明,9煤层孔隙度、最大甲烷吸附量明显高于其他煤层,储层特征形成了瓦斯异常的基础;在研究区西部、中部及东部瓦斯涌出量随深度均呈增大趋势,9煤层瓦斯重点防治区域主要分布于研究区中部及两侧深部。
        In order to find out the abnormal causes of high gas emission in 9 coal seam, gas emission of9 coal seam is predicted and comprehensive hazard zoning is carried out. The results show that the porosity and maximum methane adsorption of 9 coal seam is obviously higher than that of other coal seams, and reservoir characteristics have formed the basis of gas anomaly. In the west, middle and east of the study area, the amount of gas emission increases with depth. The key prevention area of 9 coal seam gas is mainly distributed in the middle part of the study area and the deep part of both sides.
