对突出做功的瓦斯内能的研究

介绍了突出模拟实验室研究瓦斯内能对突出做功的研究成果。通过模拟突出过程中煤的破碎和抛出,并对瓦斯破碎煤样与机械功破碎煤样进行破碎程度及能量对比分析,得出了瓦斯内能对突出做功的定量关系式。

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.
