崔庙煤矿瓦斯赋存主要影响因素及突出危险性分析
Analysis on Influence of Geological Factors on Gas Storage and Outburst Risk in Coal Seam of Cuimiao Coal Mine
【摘要】 为研究地质因素对煤层瓦斯赋存的影响,通过收集崔庙煤矿现场勘测数据并进行整理研究,基于地质构造,煤层厚度,煤体强度,煤层围岩及埋深对瓦斯赋存的影响的重要性,提出了影响其主采煤层二1煤层瓦斯赋存的主要因素,研究结果表明:煤层埋深为其主要影响因素,而地质构造也具有重要影响。
【Abstract】 The survey data from Cuimiao coal mine had been researched to identify the importance of geological factors on the coal seam gas content.Based on the relation between the gas content and related factors,the geological structure,coal thickness,coal and surround rock’s strength as well as the seam depth,the paper had worked out the priority determinants on seam gas content in the 2-1th seam,the major seam of Cuimiao mine coal.The result shows that the coal seam depth takes the first place to determine the gas content,and the geological structure is followed.
