通过对低阶煤矿区开拓巷道掘进过程中造成H_2S气体异常的地质特征、围岩性质、地下水分布、煤变质程度、原煤硫分等5个方面进行分析,认为该矿H_2S的形成为BSR成因类型。并对H_2S异常区域提出有效的防治措施,对矿井安全生产具有一定指导作用。对于矿区西部的1#煤高硫区和周边的4~#煤高硫区,应高度重视H_2S异常。
Through analyzing the geological characteristics, surrounding rock properties, groundwater distribution, degree of coal metamorphism and the sulfur content of raw coal caused by the development of roadway in low-grade coal mine, it is considered that the formation of H_2S in this mine is of BSR genetic type . And puts forward effective prevention and control measures for H_2S anomalous area, which will play a guiding role in mine safety production. For the 1 # coal high sulfur area in the west of the mining area and the 4 ~ # coal high sulfur area in the periphery, the H_2S anomaly should be highly valued.
