火成岩侵入特厚煤层巷道支护技术研究
Study on control of surrounding rock of tunnel with very thick coal seam intruded by igneous rock
摘要
Abstract
Due to the stability controlling problem of very thick coal seam which intruded by igneous rock of carboniferous system in Datong coal mine field,the deformation and failure characteristics of surrounding rock of tunnel were analyzed,and the corresponding control technology was put forward.Field test of rock mass strength and observation of deformation of roadway were conducted.The result shows that the surrounding rock of very thick coal seam which intruded by igneous rock displays the properties of structural rheological behavior.Based on this,high pre-stress and yielding supporting technology was proposed.Research achievement was successfully used in Tashan coal mine second mining area tunnel supporting project.关键词
