摘　　要：为了减少煤矿支护不当造成的巷道损害,利用数值模拟软件对不同锚杆长度及不同间排距下的巷道围岩变形进行研究,确定最佳锚杆长度为2200mm,最佳间排距为900mm、900mm。根据模拟结果进行支护方案设计,并对支护设计的可行性进行研究,发现支护后巷道顶板变形得到有效控制,为矿井安全开采提供依据。In order to solve the damage caused by improper support in coal mines, numerical simulation software was used to study the deformation of the roadway surrounding rock with different anchor lengths and different inter-row distances, and the optimum anchor length was determined to be 2 200 mm and the optimum inter-row distance was 900 mm×900 mm. It was found that the deformation of the roadway roof was effectively controlled after shoring, which provided a basis for safe mining.
