Laws of Mining Strata Pressure of Thin Coal Seam Working Face Under Goaf in Nantun Coal Mine
摘要
Abstract
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.关键词
