锚杆支护是进行巷道掘进中重要的支护方式，对维护煤矿的安全具有重要的作用。针对某煤矿围岩变形的问题，采用探地雷达进行实际测量，并以此对所使用的锚杆长度进行优化，选择3 m长锚杆进行支护，对不同锚杆间距及排距作用下围岩的变形进行仿真模拟，对围岩的变形量进行统计。结果表明，锚杆支护的间距及排距不同对巷道围岩不同位置的影响作用不同，在间距700 mm、排距800 mm 时巷道围岩的变形量最小，具有较好的支护效果。
Analysis of Simulation Study on Optimisation of Row Spacing between Anchor Supports
Anchor support is an important support method in roadway excavation,which plays an important role in maintaining the safety of coal mine.For the deformation of the surrounding rock in a coal mine,ground-penetrating radar was used to carry out actual measurements and optimise the length of the anchors used,and 3 m long anchors were selected for support,and the deformation of the surrounding rock under the action of different anchor spacing and row spacing was simulated,and the deformation of the surrounding rock was statistically calculated.The results show that the different spacing and row spacing of anchor support have different effects on different locations of the roadway surrounding rock,and the deformation of the roadway surrounding rock is the smallest when the spacing is 700 mm and the row spacing is 800 mm,which has a better support effect.
