Abstract

The article shows the results of research on methane concentration changes along mine galleries. The experiment was conducted in a longwall area mined using a U-type system, and the results were obtained in situ. The main goal was to measure methane concentration by function of gallery length and dividing segments of methane data into segments, which ultimately enabled separate analysis of these methane data. The analysis led to the diagnosis of methane hazard through the detection of exceedance of the assumed tolerance area.

煤矿井下巷道甲烷排放测量

文章展示了对矿井巷道沿线甲烷浓度变化的研究成果。实验是在使用 U 型系统开采的长壁区域进行的，结果是在现场获得的。主要目标是根据巷道长度的函数测量甲烷浓度，并将甲烷数据分段，最终对这些甲烷数据进行单独分析。分析结果通过检测超出假定容许范围的情况，诊断出甲烷危害。
