在分析国内外煤与瓦斯突出理论研究的基础上,研究了目前煤与瓦斯突出研究存在的问题,提出了用气球模型模拟煤与瓦斯突出,发现其预防的关键是如何准确确定临界状态的产生时间,即何时气球的内的气体压力与煤岩硬度达到一种相对稳定的临界状态。
Based on the analysis of domestic and international coal and gas outburst theory research, the existing problems of coal and gas outburst research are researched. The balloon model is used to simulate the coal and gas outburst, and the key to prevent it is how to accurately determine the critical state Time, that is, when the gas pressure inside the balloon and coal rock hardness reaches a relatively stable critical state.
