摘要
丰城矿务局的3对矿井每年采掘巷道达万余米,在大断面煤巷采用右旋热扎矿用树脂锚杆支护,能有效解决原有锚杆支护材料在锚杆支护中存在的缺点,较好地解决了煤巷施工及巷道维护变形的问题。
Every year, the drilling distance of roadway is up to 10,000m in three collieries of Fengcheng Mining Bureau. Bolting with right--peel hot rolling mine resin is used on cross--section coal roadway, which can solve not only the existing shortcomings of old bolting material, but also the deformation problems of construction roadway and roadway maintenance
