摘　　要：钻井法凿井技术在淡水环境中的应用已非常成熟,但在高浓度盐水环境中的应用在国内尚属空白。本文通过试验对盐水环境下壁后填充材料的力学性能和强度发展规律进行研究,可为钾盐矿采用钻井法凿井施工提供借鉴。Shaft drilling method is used successfully in fresh water environment, but never used in high concentration brine in domestic.In this paper the mechanical properties and strength development law of backfill materials in high concentration brine were studied,which could provide reference for the shaft drilling of potash deposit.

关 键 词：钻井法 壁后充填材料 抗压强度
