To simulate the in situ influence of pressure,temperature and other factors on the mechanical performance of cemented backfill in a laboratory environment,this paper designed a testing apparatus considering the cooperative control of ap-plied pressure and temperature during the curing of cemented backfill samples.The influence of applied pressure and environ-mental temperature during curing on the early-age strength of cemented backfill samples was studied.The results show that both curing pressure and curing temperature have a noticeable influence on the early strength of cemented backfill samples.The cu-ring pressure is beneficial to the early strength development of cemented backfill samples.With the increase in curing tempera-ture,the strength of the cemented backfill samples initially raised as well,then decreased while the curing temperature reached 55℃.Under the coupled influence of curing pressure and curing temperature,high temperature is beneficial to the early strength development of cemented backfill samples.
