摘要
为研究采空区下薄煤层工作面矿压规律,以南屯煤矿17#薄煤层工作面为例,采用理论分析、现场实测、数值模拟等方法,研究了采空区下薄煤层综采工作面覆岩结构及来压特征,分析薄煤层工作面覆岩裂隙带与上覆采空区"三带"的导通性,保证了现场工作面安全顺利回采。
In order to study the laws of underground pressure in thin coal seam working face under goaf,by the means of theoretical analysis,field test,numerical simulation,taking an example of thin coal seam working face in Nantun Coal Mine,the paper studies the overburden strata structure and characters of strata pressure of thin coal seam working face under goaf,and analyzes connectivity between fractured zone of 17~# thin coal seam working face and upper goaf,which ensures the safe and smooth mining of working face.
