A New Model for Coupled Rock-coal Deformation and Gas Leak Flow in Mining Engineering

Peide Sun

Abstract:
Underground coal seams are mostly distributed in adjacent multi-layers in most countries of the world, especially in China. Many problems in mining engineering and rock engineering remain unsolved and these problems, in essence, are linked with rock mass deformation and gas leak flow by Sun. From the viewpoint of interaction mechanics for solid and gas, a coupled mathematical model is presented for coal/rock visco-elastic-deformation and gas leak flow in parallel deformable coal seams. The new mathematical model consists of equations for gas leak flow, equations for solid coal/rock mass visco-elastic-deformation and boundary/initial conditions.
