The dump of open-pit coal mine is reconstructed by loose soil-rock mixture under the action of gravity, dynamic load of transportation equipment, blasting vibration and so on. Due to the saturated state of rainfall or groundwater flow, if the drainage is not timely, excess pore water pressure will occur in the remolded slope of the dump, and the sliding resistance of the slope will be reduced. In order to simulate the working condition, the compression-seepage coupling characteristics of soil-rock mixtures under saturated pore water pressure were tested under three factors: particle size, rock content and loading rate. The experimental results show that the soil-rock particles in the area affected by pressure change in vertical direction step by step, and the displacement field formed by soil-rock particles is similar to bowl shape. With the increase of sand particle size, the influence range of displacement field of soilrock mixtures decreases gradually, and the range of displacement field of soil-rock mixtures synthesized with 0.1-0.5mm sand particle size is the largest. With the increase of rock content, the influence range of displacement field of soil-rock mixtures becomes smaller. The loading rate has little effect on the displacement field of soil-rock mixture.
