针对安徽某铁矿全尾砂胶结充填项目进行了单轴抗压强度试验、剪切试验、三轴压缩试验,得到不同条件参数下的抗压强度、抗剪强度和围压状态下的C,φ值,研究结果表明,砂灰比为6、砂浆浓度为72%时,在兼顾料浆输送和成本的同时,可以保证充填体的强度。 According to the uniaxial compressive strength test, shear test and triaxial compression test of a tailings cementing project in a certain iron mine in Anhui Province, the compressive strength, shear strength and confining pressure under different conditions were obtained, φ value, the results show that when the ratio of sand and gravel is 6 and the mortar concentration is 72%, the strength of the filling body can be ensured while taking into account both the conveying of the slurry and the cost.
