小型正断层对掘进工作面瓦斯异常涌出的影响分析

Research on the impact of small normal faults on abnormal gas gush in the dig working face of coal mines

基于地质构造对于瓦斯赋存的控制作用,分析了山西潞安矿区常村以及五阳井田小型断层的特征,并且结合生产过程中掘进工作面的瓦斯涌出量的实测数据,通过分析瓦斯涌出量变化与断层的落差和倾角之间的数学联系,得出了瓦斯涌出量的异常增长与断层落差之间具有一定的相关性.这一结论对于掘进工作面瓦斯涌出量预测以及煤与瓦斯突出预防具有一定的指导作用.

Based on the effect of the geological structure on gas deposits, we analyzed the features of small faults of Changcun coal mines and Wuyang coal mines in the Lu＇an mining area of Shanxi Province in China. Based on the dig working face gas gush amount data in the production process, it was found that there was a linear relationship between the abnormal growth of gas gush amount and the fault throw. This conclusion has guiding significance for gas emission prediction in dig working faces and the prevention of coal and gas outbursts.
