绿水洞矿井地质构造特征与瓦斯赋存规律分析

Analysis on Geological Structure Features and Gas Deposit Law in Lüshuidong Mine

通过对绿水洞矿井的区域地质演化情况和地质构造特征进行分析,结合井下采掘过程中揭露的地质构造及其采掘工作面的瓦斯涌出数据,研究了井田瓦斯赋存的规律,揭示了地质构造特征与瓦斯赋存状况两者之间的关系,分析了影响绿水洞矿井K1煤层瓦斯分布的主要控制因素,指出褶皱、断裂构造控制着井田瓦斯赋存,是造成瓦斯赋存复杂性的主要原因。并对井田深部煤层瓦斯的赋存状况进行了预测,对矿井后期的安全生产具有一定的指导作用。

With the analysis on the local geological evolution and geological structure features of Lushuidong Mine, in combined with the geological structure exposed from the underground excavation and mining operations as well as the gas emission data of the excavation and mining faces, the paper studied the minefield gas deposits law, released the relationship between the geological structure features and gas deposits conditions and analyzed the main control factors affected to the gas distribution of Kl seam in Ltishuidong Mine. The paper pointed out that the folded and fracture structures controlled the minefield gas deposits and were the main causes to occur gas deposits complicated. A prediction on the seam gas deposits in the minefield deep section was conducted, which would have certain guidance to the safety production of the mine in later.
