云南省镇雄县马河向斜煤矿区C5煤层瓦斯地质规律研究

Study of C5 Coal Seam Gas Geology Regularity of Mahe Syncline Mining Area in Zhenxiong County of Yunnan Province

云南省镇雄县马河向斜煤矿区矿井众多,瓦斯事故频发。该区总体为一向斜,瓦斯含量1.82~18.04 m3/t,平均7.95 m3/t。通过分析矿区地质构造、煤层厚度、煤的变质程度、煤层埋深、水文地质条件等影响瓦斯含量的地质因素发现,该区的瓦斯分布规律总体上受向斜控制。主要介绍了马河向斜煤矿矿区概况,详细分析了矿区瓦斯分布特征和影响瓦斯赋存的各种地质因素,以期为相关方面提供一定的参考和借鉴。

Mahe Syncline Mining Area in Zhenxiong County of Yunnan Province is numerous, gas accidents. The area is generally syncline, and gas content from 1.82 to 18.04 m3/t, and average is 7.95 m3/t. Through the analysis of the geological structure, coal thickness, coal metamorphism degree, coal buried deep, hydrology and geology conditions affecting gas content of the geological factors, the law of gas distribution on the whole by syncline is found. This article mainly introduces the horse Creek syncline coal mining area survey, detailed analysis of the mine gas distribution characteristics and influencing gas occurrence of various geological factors, in order to provide certain reference and reference.
