摘　　要：在煤矿兼并重组建设设计施工过程中,为了更好的满足安全高效生产要求,需沿采空区或小窑破坏区布置掘进煤层巷道,通过分析采空区巷道围岩破坏特征,并根据采空区附近煤体破坏实际,发现了现有巷道设计保安煤柱计算公式的不足。以松动圈理论为基础,对计算公式进行修正,提出一种简单可行的计算公式,以期解决目前山西省资源整合煤矿设计中遇到的采空区巷道保安煤柱计算理论依据不足的现状。In the process of construction design for coal mine merging and reorganization,in order to better meet the requirements of safe and efficient production,we need to arrange seam excavation roadway along goaf or minitype coal mine breaking area. Through the analysis of breaking features of goaf roadway surrounding rock,according to the real failure of coal mass around goaf,we find out that the insufficient of calculation formula in coal pillar design. Based on the theory of loose circle,we revise the calculation formula,and propose a simple calculation formula to solve the status which is lack of theory basis in goaf roadway safety coal pillar design of Shanxi Province resource integration mines.
