摘要
本文根据碱场煤矿深部巷道矿压显现特征和巷道围岩松动圈测试结果，提出了深部返修巷道支护方式─—快硬膨胀水泥锚杆加菱形金属网支护；依据现场实测结果，分析了返修巷道特有的矿压显现规律；在总结和分析深部返修巷道锚网支护技术成功的经验基础上，对深部返修巷道锚网支护参数和断面形状的确定提出了相应的看法和建议。
According to the feature of strata behaviorin deep workings and the measurement results ofconcussion circle in roadway surrounding rock of Jianchang Coal Mine, this paper put forward the supporting type used in deep workings repaired,which is the combined support using the rapidhardening and swelling cement grouted belt andthe rhombus mesh.According to the siteobervation,this paper analyzed the peculiarrule of strata behavior in deep workingsrepaired.Based on summarizing and analyzingthe experience of combined support usingshotcrete and bolting wire mesh in deep workingsrepaired,this paper put forward correspondingto view and suggestion for determining supporting parameters and Section figure of deepworkings repaired.
