Study on Intrinsic Gas Energy to Do Work in Outburst

Based on the summarization of research achievements both at home and abroad,the paper describes research results of intrinsic gas energy to do work in outburst through simulated experimental study of outburst. Comparative analysis is made on the breaking degree of coal sample and energy on it under the action of both intrinsic gas energy and mechanical work by simulating the breaking and throwing-out of coal in the process of outburst,and a quantitative relational expression about the intrinsic gas energy to do work in outburst is obtained.
