【摘要】：為研究粒度對長焰煤瓦斯放散規(guī)律的影響,通過建立能夠容納大質(zhì)量煤樣的吸附解吸實驗系統(tǒng),模擬煤樣的放散過程。以粒度變化為主要因素,研究不同破壞類型的干燥煤樣在恒溫(30±1)℃和恒壓0.74MPa條件下的長焰煤瓦斯放散規(guī)律,并結(jié)合軟硬煤的孔隙結(jié)構(gòu),分析不同煤樣的瓦斯放散量、放散初速度的差異性。
[Abstract]:In order to study the effect of particle size on the gas emission law of long flame coal, an experimental system of adsorption and desorption was established to simulate the release process of coal samples. Taking the change of grain size as the main factor, the gas emission law of long flame coal under constant temperature (30 鹵1) 鈩，
