Roadside filling material
The invention relates to a paste roadside filling material prepared by utilizing low-cost multi-component solid waste synergistically. Materials can be fully mixed through a one-pot method, use of two or more stirring devices is avoided, output through multiple pipelines is not needed, the material and device input cost is lower, and the filling efficiency is high. By changing the water-cement ratio of the material, mechanical continuous and rapid filling can be guaranteed, enough supporting resistance is provided for a top plate in time, and the stability of an overlying rock layer is guaranteed. The requirements of the roadside filling gob-side entry retaining project are met, meanwhile, resource utilization of a large amount of solid waste is achieved, resources and energy are saved, and the local ecological environment is improved.
本发明涉及利用低成本多组元固废协同制备膏体类巷旁充填材料。可将物料进行“一锅法”充分混合，避免了两个或多个搅拌设备的使用，无需多个管道输出，材料和设备投入的成本更低，充填效率高。通过改变材料水灰比，可保证机械化连续快速充填，对顶板及时提供足够的支护阻力，保证上覆岩层稳定。在满足巷旁充填沿空留巷工程需要的同时，实现大宗固废的资源化利用，既节约了资源能源，又改善了当地的生态环境。
