Deep Underground Science and Engineering, EarlyView.The influence of gas on the instability and failure of rock–coal–rock combinations is considered. The damage characteristics of gas‐bearing rock–coal–rock combinations under different confining pressures, axial loading rates, and gas are revealed. A constitutive model for gas‐bearing rock–coal–rock damage considering gas is established.

Deep Underground Science and Engineering, EarlyView.In this study, the nonuniform distribution of the bearing pressure in front of the coal wall has been revealed based on in situ monitoring data and numerical simulation results. Therefore, an eccentric compression mechanical model of the coal wall was established to study the deformation and failure characteristics of a coal wall. The slenderness ratio

Assessment of practicality of remote sensing techniques for a study of the effects of strip mining in Alabama [PDF]
Because of the volume of coal produced by strip mining, the proximity of mining operations, and the diversity of mining methods (e.g. contour stripping, area stripping, multiple seam stripping, and augering, as well as underground mining), the Warrior ...
