According to the in situ environments of deep copper mines, the authors have developed new types of underway LHD roads, including a cement mine waste concrete road, a plaster mine waste concrete road, a composite jelling agent ore powder concrete road and a block mine waste rolled road, ensuring high intensity underway transport.
针对深部铜矿井下采场铲运机运行路面的具体情况,开发以井下矿碴为骨料的水泥、石膏、复合胶凝剂矿粉混凝土路面及块状矿碴辗压路面,为高强度井下采矿作业提供了运输保障,与传统的砂料混凝土路面相比,技术经济效益显著。
The concrete with massive micro-cinder powders has contributed a lot to anti-corrosion from seawater, so which is spreading on hydraulic engineering programs in coastlands of Guangdong province.
大掺量矿碴微粉混凝土在抵抗海水腐蚀方面有显著的效果 ,广东省在沿海地区修建的水利工程推广使用该项技术。
