摘要:
覆岩采动裂隙演化规律及其形态特征与卸压瓦斯抽采密切相关。运用自主设计的固气耦合相似模拟实验系统，通过模拟实验分析得到采动裂隙随着工作面的推进经历了产生、发展和闭合过程，其分布曲线呈马鞍状。结合采动裂隙演化规律及分布形态，分析了采动裂隙场的演化特征，其发育高度受主关键层影响明显，进一步明确了卸压瓦斯在裂隙发育各阶段发生运移和汇集的区域范围，为现场布置瓦斯抽采钻孔参数提供了设计依据。
Abstract:
The evolution laws and distribution features of mining fissure in overlying strata are closely related to the degasification of relieved methane. Using physical similar simulation experiment, it is obtained that the generation of mininginduced fissure has three stage, development, expansion, closed, and its pattern is “Saddle". With the evolution laws and distribution of mining fissure, the characteristics of mining fissure field is analyzed, the height of fissure is affected by key layer, the released gas seepage and reservoir area is determined in the different stage of mininginduced fissure development. It provides the foundation for conveniently and reasonably arrangement parameters of drill hole of relieved methane.
