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.

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.
