| 摘 要： | 含瓦斯煤层开采使工作面煤壁前方煤体及顶煤乃至顶板的原生结构遭到破坏,顶煤从煤壁前方始动点开始运移至放煤口经历了复杂的过程,煤岩体中的孔隙率也随之发生变化,致使煤岩体中瓦斯的赋存状态和运移形态亦相应发生变化,分析其变形特征可更好的认识放煤规律及煤体瓦斯运移特性。本文根据亭南煤矿101综放面的矿压观测和瓦斯监测结果,得出了综放面围岩移动影响下的采场瓦斯涌出特征,为有效地指导含瓦斯特厚煤层的综放开采,防治瓦斯事故以及合理抽取利用瓦斯资源提供了理论依据和技术支持。

| Abstract: | The mining of coalbed with high gas destroyed the coal in frontage of workface,the top-coal and the original texture of roof.The top-coal comes through complicated course from movement to giving out.The hole rate of coal is following changed,all those make corresponding changes of the modes of occurrence and transport pattern of gas in coal.Analyzing the distortion character can better identify the top coal caving law and the gas delivery characteristics.The text based on the result by underground pressure observation and gas monitor for the 101 working face in the Tingnan coal,educed the characteristics of gas emission under the infection of surrounding rock in fully mechanized top-coal caving(FMTC) face.It provides theoretical base and technical support to direct fully mechanized sublevel caving,effectively preventing gas disaster and reasonable draining and using of gas resource. |
