Numerical Simulation Study on Mechanical Properties of High-Pressure Water Injection Coal Seam
High-pressure water injection is an emerging measure to eliminating the coal and gas outburst, and commonly used in coal mine. But people cant enough know about stress evolution, softening zone distribution and water seepage law during highpressure water injection, which lead to determine some construction link depend on experience. In order to make clear those problems, numerical simulation of coal high-pressure water injection was studied base on fluid-solid coupling model of coal rock damage to analyze coal rock mechanical properties. It was helpful for construction of high-pressure water injection.
