摘要
由于现阶段瓦斯解吸试验采样数量少、范围小、实测数据与瓦斯解吸模型计算结果之间有误差,故在多个矿井采集煤样开展解吸试验,以此扩大煤样的采集范围;采用控制变量法,通过改变煤样的吸附平衡压力、粒度以及温度3个变量,来研究不同情况下瓦斯解吸时变规律。对不同赋存条件下的煤样进行解吸试验,以此增强瓦斯解吸模型的适用性,再次检验影响瓦斯解吸的主控因素。
Due to the small sampling quantity and scope of gas desorption test and the error between measured data and calculation results of gas desorption model,coal samples were collected in several mines to carry out desorption test,so as to expand the collection range of coal samples.The time-varying law of gas desorption under different conditions was studied by changing three variables of coal sample adsorption equilibrium pressure,particle size and temperature by using control variable method.Desorption tests were carried out on coal samples under different occurrence conditions to enhance the applicability of gas desorption model and check the main control factors affecting gas desorption again.
