Results showed that deep mine temperatures have a significant effect on the properties of CPB. Increasing the curing temperature increases the rate of CPB strength development
Results showed that deep mine temperatures have a significant effect on the properties of CPB. Increasing the curing temperature increases the rate of CPB strength development and leads to higher early CPB strength and lower binder consumption.
With natural cooling, the stress-strain curve features double. peaks in the range of 200-300°C, whereas such phenomenon occurs at temperatures. greater than 300°C with water cooling. (c) When the temperature is less than 300°C, no obvious change occurs in

15/8/2020 Cemented paste backfill (CPB), a mixture of tailings, binder, and water, is widely and extensively used for the recovery of mineral resources, the prevention of ground subsidence, and the management of mine waste. When installed, the CPB is subjected to complex environmental conditions such as water content, temperature, and power, which have a significant impact on its efficiency.
