Industrial solid waste-based inorganic paste filling material, preparation method and rapid filling method
The invention provides an industrial solid waste-based inorganic paste filling material, a preparation method and a rapid filling method, and belongs to the technical field of mine filling. The industrial solid waste-based inorganic paste filling material provided by the invention is prepared by mixing coarse aggregate, fine aggregate and a solid waste filling cementing material. The rapid filling method comprises the steps that the industrial solid waste-based inorganic paste filling material is taken and conveyed to the underground through a ground feeding hole, then the industrial solid waste-based inorganic paste filling material is evenly mixed with mine water, and the goaf is filled with the obtained paste filling slurry. The industrial solid waste-based inorganic paste filling material does not need underground weighing and can be directly added with water for use, and compared with an existing paste filling process, and the difficulty of underground classified conveying of various solid materials is reduced; meanwhile, the space occupancy rate of underground equipment and a weighing system is also reduced, the underground working intensity is reduced and the safety coefficient and the working efficiency are improved.
本发明提供了一种工业固废基无机膏体充填材料、制备方法及快速填充方法，属于矿山充填技术领域。本发明提供的工业固废基无机膏体充填材料，是取粗骨料、细骨料和固废充填胶结材料混合制得。所述快速填充方法是取所述工业固废基无机膏体充填材料，经地面投料孔运至井下，再与矿井水混合均匀后，所得膏体填充浆料对采空区进行填充。本发明工业固废基无机膏体充填材料，无需井下称量、可直接加水使用，与现有的膏体充填工艺相比，减少了各种固体物料井下分类输送的难度，同时也减少了井下设备及称量系统的空间占用率，降低了井下工作强度，提高了安全系数与工作效率。
