Article Synopsis
- - The Wuyang coal mine's 8002 high-gas working face experiences significant challenges during excavation due to high gas pressure and ground stress, leading to safety concerns such as exceeding gas concentration limits and potential disasters.
- - A study focused on the effectiveness of large-diameter boreholes for pressure relief was conducted, utilizing a damage-stress-seepage model and analyzing how variables like borehole diameter and initial gas pressure affect gas distribution and stress in coal seams.
- - Findings indicate that a 250 mm borehole aperture is optimal for pressure relief, creating a broader plastic zone when arranged in a "three flower holes" configuration with 1.4 m spacing, while increased initial gas pressure raises vertical stress above the boreholes
Tailings can be used as embankment materials instead of sand. However, they contain large amounts of heavy metal pollutants, which can lead to groundwater pollution. In this study, (lead-zinc) Pb-Zn tailings with five particle sizes and Sporosarcina pasteurii were used as test materials.
