煤与瓦斯突出能量的研究

利用研制的煤与瓦斯突出模拟实验装置,对芙蓉、丰城、乐平、涟邵、白沙、梅田、六枝等煤与瓦斯突出重点局矿的19个煤样进行了98次机械功破碎实验、123次瓦斯内能破碎实验,并对19个煤样进行了工业分析、坚固性系数测定、放散初速度测定等实验,在此基础上,建立了以地应力、瓦斯压力、煤的坚固性系数及放散初速度表述的发生煤与瓦斯突出的能量关系式,并对六枝矿务局化处矿一次突出进行了具体分析。

Study of Coal and Gas Outburst Energy

Using Simulating Experimental Device of coal and gas outburst developed by ourselves, 98 fragmentation experiments under mechanical energy and 123 fragmentation experiments under gas internal energy were done with 19 coal specimens taken from the major outburst mines and bureaus including Furong, Fengcheng, Leping, Lianshao, Baisha, Meitian, Liuzhi, etc. Industry analysis, the measurement of solidity coefficient and measurement of initial gas emission velocity on these coal specimens were also conducted. Based on above experiments and measurements, a relational expression of coal and gas outburst energy expressed by strata stress, gas pressure, coal solidity coefficient and initial gas emission velocity was established, and specific analysis was made on an outburst occurred in Huachu Mine of Liuzhi Coal Mining Administration.
