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。

Comparison between the results of hydraulic test and the prototype observation of rock stopple burst in Xianghongdian Pump Storage Power Station shows that the hydraulic model of rock stopple burst can simulate the shape of broken rock in the collection pit and the surge height in the gate well.
