摘要
通过对锚杆加固小煤柱护巷机理的分析,并模拟不同支护形式下小煤柱巷道的稳定性和围岩变形量,得出高强锚杆支护可有效控制巷道围岩变形,保证巷道安全和煤柱稳定,是小煤柱巷道最有效的支护形式。
This paper analyzed supporting mechanism of roadway with anchored bolt in small coal pillar and simulated roadway stability and surrounding roekg deformation of roadway in small coal pillar. Result showed that anchored bolt with high strength could control effectively deformation of surrounding rock and anchored bolt was most effective supporting manner for roadway safe and pillar stable.
