五阳煤矿3号煤层瓦斯地质规律分析及研究

Study and analysis of gas geology law in NO.3 coal seam of Wuyang Coal Mine

分析了井田内地质构造控气特征,简述了五阳煤矿3号煤层瓦斯赋存地质规律主要受构造、煤层埋深、底板标高、上覆基岩厚度、煤层顶底板岩性、厚度等多种地质因素的影响。通过定量与定性相结合进行分析,运用线性回归方程得出影响煤层瓦斯分布规律的不同关系,对公式进行对比分析,得出煤层埋藏深度是煤层瓦斯含量的主控因素,为矿井下一步防治瓦斯治理提供理论依据。

Based on analysis of geological structure gas controlled features in field, NO.3 coal seam gas hosting law in Wuyang influenced by various geological factors of structure, coal seam buried depth, floor elevation, overlying bedrock thickness, roof and floor lithology and thickness was described. Different relationship of affecting seam gas distribution rules was derived from linear regression equations through combination of quantitative and qualitative analysis. According to formula comparative analysis,buried depth of coal seam was the main factor in coal seam gas content, which provided theoretical foundation to prevent gas control.
