Preparation method of cementing material for cemented filling of high-sulfur tailings
The invention discloses a preparation method of a cementing material for cemented filling of high-sulfur tailings. The preparation method comprises the following steps: S1, sorting and pretreating materials; s2, stirring and mixing; s3, carrying out solid-liquid separation and drying; s4, high-temperature processing and grinding; the material prepared by the method has excellent performance, has few internal holes after being filled, is low in bleeding rate, high in strength and stable in performance, and can keep a good plugging and supporting effect under the condition of liquid seepage in a mine subsidence area for a long time.
本发明公开了一种高硫尾矿胶结充填用胶凝材料制备方法，包括步骤：S1、材料分选预处理；S2、搅拌混合；S3、固液分离干燥；S4、高温加工及粉磨；采用本方法制备的材料，具备优秀性能，填充后内部空洞少、泌水率低，强度高，性能稳定，能够在长时间的矿洞塌陷区具有液体渗出的情况下保持良好的封堵支撑效果。
