A Case Study on the Gas Drainage Optimization Based on the Effective Borehole Spacing in Sima Coal Mine
Based on the dynamic expressions of permeability and porosity of the coal seam derived in the paper, a multiphysical field coupling numerical model of gas migration under the interaction of stress field and seepage field was established. The gas drainage project #3 Coal Seam operated by Sima Coal In...
