倾斜厚煤层错层位相邻巷道联合支护技术
Combined Support Technology of Adjacent Roadway by Staggered Outward Arrangement in Inclined Thick Seam
摘要
Abstract
For the further study of inclined thick coal seam supporting technology,using theoretical analysis and numerical simulation,we study deep roadway surrounding rock stability problems,and thick that the basic control method of deep roadway is the transfer of high rock stress to improve the rock strength,and to adopt the rational supporting technology.We propose the staggered outward arrangement adjacent roadway combined support technology.In this paper,taking Pangpangta Mine as the engineering background,the supporting effect of the single lane layout and staggered outward arrangement under two kinds of situations is compared;regression analysis is carried out for anchorage strength of adjacent roadway combined support zone by staggered outward arrangement.The analysis shows that the anchorage strength of adjacent roadway combined support zone by staggered outward arrangement is superior to single lane anchorage strength.关键词
