【摘要】：为研究粒度对长焰煤瓦斯放散规律的影响,通过建立能够容纳大质量煤样的吸附解吸实验系统,模拟煤样的放散过程。以粒度变化为主要因素,研究不同破坏类型的干燥煤样在恒温(30±1)℃和恒压0.74MPa条件下的长焰煤瓦斯放散规律,并结合软硬煤的孔隙结构,分析不同煤样的瓦斯放散量、放散初速度的差异性。
[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 卤1) 鈩，
