Study of Rational Water Injection Parameters of Hydraulic Pressing Preventing Outburst Measure based on Numerical Simulation

摘要：

With the increase of the mining depth in coal mine, the safe producing of mine is seriously restricted by outburst danger of driving working face of coal road. For solving the problem, in this paper, mechanics model is created about Hydraulic Pressing Preventing Outburst Measure through theory analyzing. Finite element software ANSYS is used to simulate the models under the conditions of different water injection parameters based on parameters measured in-site. The rational length of hole, pressure and arrangement of hole after injecting water is determined through analyzing the distribution of stress and change of displacement in coal seam. The theory significance of the method is great for construction in-site.
