含瓦斯煤带压解吸规律的实验研究
Experimental study on gas pressure desorption law governing coal containing gas
摘要
Abstract
This paper seeks to obtain the desorption law of coal containing gas and increase the efficiency of gas extraction by experimental study under pressure and gas desorption process under atmospheric pressure. The results show that: Gas desorption of coal containing gas belongs to pressure desorption during gas extraction process, the gas under pressure gives smaller desorption volume and lower desorption rate than does the gas under atmospheric pressure, and gives a significantly delayed desorption termination than the gas under atmospheric pressure. It follows that the evaluation of extraction admissibility of gas-containing coal and the determination of the termination time of gas extraction are determined by the desorption index under pressure as a measure index. The study is of value for guiding field extraction of gas resources.关键词
