Numerical Simulation of Gas-Water Dual Media in the Process of Coal Seam Hydraulic Extrusion

Abstract:

Assuming that the flow of water and gas in the coal seam fracture system to follow Darcy flow law, according to multiphase fluid flow mechanics and porous media fluid mechanics theory, this paper establishes gas-water dual media in the coal seam hydraulic extrusion coupled seepage model. Make use of this model simulates the main technical parameter injection pressure of the coal seam hydraulic extrusion, and compared to actual injection pressure of Huai river mining area, the results are in agreement. This model provides a reference to optimize the main techinical parameters of the coal seam hydraulic extrusion.
