| 摘 要： | 通过对新集矿21个煤样进行解吸和热解试验,绘制出了氢气浓度与煤温的变化关系曲线,分析研究了新集煤矿井下采空区氢气的来源,提出了新集煤矿煤中吸附有氢气,并在常温下可解吸出来,以及氢气的生成量随煤温升高而增大的结论。

Experimental Study of Hydrogen Source Determination in Gob of Xinji Coal Mine |
| |
| Abstract: | Based on the desorption and pyrolytic test of21coal sam ples taken from Xinji Mine,the au thor drew up the rela tion curve of the variation of hydrogen concentration with coal tem pera ture,made analysis and study on the hydrogen source in the gob in Xinji Mine and reached the conclusions that hydrogen is absorbed in Xinji,it can des-orbed from coal at normal tem perature and the hydrogen gen eration in-creased with the rise of coal temperature. |
