多煤层回采留煤柱护巷技术
Technology of chain-pillar entry protection in multiple seam stope
摘要
Abstract
In order to solve the deformation and failure of coal seam protection coal pillar roadway in multiple seam stope,this paper took two adjacent working face in NanYangPo coal mine as case of research,based on the determining of coal pillar width and stagger distance,determined the coal pillar size and supporting method for the roadway on the basis of the field monitoring,theoretical analysis and numerical simulation and other research methods.The ultimately coal pillar layout scheme was determined.The results of study show that this method can effectively control the deformation of roadway surrounding rock,and deformation of roadway is leveled off in the short term;in addition,the cost of supporting is low and the coal pillar has good stability.关键词
