A METHOD FOR SIMULATING FLUID FILTRATION IN SOLID MINERAL RESERVOIRS DEVELOPED USING HYDRAULIC FRACTURING

摘要

The fluid flow modeling procedure used ABAQUS environment and the extended finite element method. The procedure is meant for calculating pore pressure distribution and gas and fluid flow directions in rock mass in the course of solid mineral mining using hydraulic fracturing. The authors discuss the standard model and case-studies of the procedure-based calculation of gas flow rates in coal seam drainage using boreholes and fractures of different orientation.
