Abstract

In order to deeply study the mechanism of coal and gas outburst，and having the further awareness and understanding of coal and gas outburst from the point of view of energy. Based on the combined effects of coal and gas outburst hypothesis，using a combination of theoretical analysis and experimental methods，analyzing the coal and gas outburst of energy dissipation mechanism，obtaining the expression of elastic potential energy and gas energy. And a mechanical model describing the coal and gas was established，owing the mathematical function formula of outburst coal and its stacking location. Then the mobile power，crushing power and friction power were calculated according to the stacking states and broken situation of outburst coal. And then，the outburst conditional expression between coal and gas outburst and the physical and mechanical parameters of coal and gas，the structural parameters of tunnel were set up. Developing the instant relief symmetry breaking coal experimental setup in the high-pressure gas，analyzing the factors of coal and gas outburst，which including the mechanical properties of the coal gas pressure，ground stress. The results showed that：The compressive strength and coal consistent coefficient of outburst coal are lower than non-outburst coal. Under the effect of gas of single factor，lower gas pressure can¢t make the complete coal crushing，ground stress has a significant impact on the coal and gas outburst. The temperature will drop in the process of coal and gas outburst.

Key words： mining engineering coal and gas outburst elastic potential energy gas energy
