The invention relates to an immobilized mining microorganism accelerant based on biosurfactant bacteria. The immobilized mining microorganism accelerant comprises immobilized biosurfactant bacteria, immobilized mineralized bacteria, an activating solution and a cementing agent. The method comprises the following steps: firstly, inoculating biosurfactant bacteria and mineralized bacteria into an activation solution to obtain a biosurfactant bacteria and mineralized bacteria fermentation solution; then, the biosurfactant bacteria and the mineralized bacteria are selectively adsorbed and enriched through the immobilized material, and the immobilized biosurfactant bacteria and the immobilized mineralized bacteria are obtained. According to the immobilized mining microbial accelerator, the hydrophobicity of the microbial accelerator applied to coal dust can be improved, and the mineralization ability can be improved and the shape of calcium carbonate crystals can be changed through mutualism between two strains of
