Distribution of methane enrichment zone in abandoned coal mine and methane drainage by surface vertical boreholes: A case study from China

Distribution of methane enrichment zone in abandoned coal mine and methane drainage by surface vertical boreholes: A case study from China

Many abandoned mines with small gobs were produced by the old mining method in China. These gobs with different widths contain a considerable amount of methane. In this paper, FLAC3D software is used to investigate the rock mass stress distributions. Based on the stress distribution results, the met...
