为了获得常压环境下煤体瓦斯解吸释放趋向性规律,利用自主设计的瓦斯解吸参数测试系统装置,在环境温度15℃、瓦斯吸附平衡压力2.0 MPa条件下,开展了垂直、平行和斜交等不同层理面煤样的瓦斯常压解吸释放对比实验,结果表明:不同的解吸层理面对瓦斯解吸参数影响显著,斜交层理面煤样瓦斯最终累计解吸量分别是垂直层理煤样、平行层理煤样的1.2倍和1.7倍,且随着解吸时间的延长趋向性差异越明显。

In order to obtain the tendency rules of gas desorption at atmospheric pressure, the comparison experiements of gas desorption and release of coal samples taken in vertical, horizontal and inclined bedding planes were carried out at environmental temperature of 15 ℃ and the gas adsorption balance pressure of 2. 0 MPa with the self-designed gas desorption parameter test system. The results showed that different gas desorption plane had significant impact on the gas desorption parameters, the final accumulative gas desorption of coal samples taken in inclined bedding plane was 1. 2 times that of the coal samples taken in the vertical plane and 1. 7 times that of the coal samples taken in the horizontal plane, and the tendency difference became more obvious with the desorption time extension.
