Description
Kun Wang and five co-authors study gas flow in coal seams under pressure-relief mining in this two thousand twenty-five paper. In deep mines, mining one seam can take pressure off another, letting trapped gas escape safely. This method guards against coal and gas outbursts, a deadly hazard. The team used a custom test rig to measure how gas seeps through coal under changing stress. They sampled two zones of the protected seam, one relieved along the axis and one across it.
Early in the tests, stress squeezed samples and set up stable seepage paths. Comparing the zones shows how direction shapes gas flow. The results explain the physics behind a widely used safety method. Mine engineers can use them to design better gas drainage.
