| 摘 要： | 文章以平煤十二矿煤样为例,分别进行了压汞实验和等温吸附—解吸实验,从构造煤的孔隙结构特征及构造煤对煤层气吸附—解吸的影响来研究十二矿构造煤煤层气特征。本次研究结果如下:①构造煤孔隙结构多以小孔和微孔为主,有利于煤层气的吸附;②煤体结构破坏越严重,对煤层气的吸附越弱;③常温下,煤层气吸附—解吸可逆。研究结果表明平煤十二矿有利于煤层气的开发。 |

| Abstract: | In order to study the coal bed methane characteristics on tectonic coal from the pore structure characteristics of tectonic coal and the effect on coal-bed methane adsorption-desorption.This paper carried out mercury intrusion experiments and isothermal adsorption-desorption experiments according to the coal samples of 12 Coal Mine of Pingdingshan.The result show that: ①many holes and microporous mainly on tectonic coal,in favor of coal-bed methane adsorption;②coal body structure damage more serious,weak the coal-bed gas adsorption;③coal bed methane adsorption-desorption reversibility under normal atmospheric temperature.Research results show that the characteristics of tectonic coal is conducive to the development of coal-bed gas in NO.12 Coal Mine of pingdingshan. |
| Keywords: | tectonic coal coal bed methane pore structure adsorption-desorption coal structure |
