Evolution characteristics analysis and engineering application of pressure-relieved gas reservoir in extra-thick coal seam mining
In order to study the dynamic evolution law of the pressure relief gas reservoir in the mining of extra-thick coal seams, the 3DEC numerical simulation software was used to analyze the stress and displacement distribution law of the overburden rock caused by mining, and the evolution characteristics...
