摘　　要：为进一步探究铁矿巷道支护工作的可能优化路径,以江西省新余市A铁矿巷道现状为案例展开研究。首先通过建模与仿真分析,确定当前该铁矿巷道支护环节存在的主要问题;其次,应用正交实验方法,对铁矿巷道支护技术参数进行优选,确定最为合理的实验组合如下:锚杆长度2.4 m,混凝土喷层厚度100 mm,可伸缩金属拱架间距0.5 m;最后对优化实验组合可取得的效果进行分析,结果显示,优化后的支护方案在减小巷道位移和塑性区体积方面均发挥出较为显著的作用,证明此方案具有潜在的应用价值。In order to further explore the possible optimization path of iron mine roadway support work,the roadway current situation of A Iron Mine in Xinyu City,Jiangxi Province was studied as a case.Firstly,through modeling and simulation analysis,the main problems existing in the roadway support link of the iron mine were determined.Secondly,the orthogonal experiment method was used to optimize the technical parameters of roadway support in the iron mine,and the most reasonable experimental combination was determined as follows:the length of bolt was 2.4 m,the thickness of concrete shotcrete layer was 100 mm,and the spacing of flexible metal arch was 0.5 m.Finally,the results of the optimized experimental combination were analyzed,and the results showed that the optimized support scheme played a significant role in reducing the displacement of roadway and the volume of plastic zone,which proved that the scheme had potential application value.
