Backfill reconstruction composition, preparation method thereof and application of backfill reconstruction composition in fine backfill of ground fracture
The invention relates to a backfill reconstruction composition, a preparation method thereof and application of the backfill reconstruction composition in fine backfill of ground fractures. Specifically, the invention relates to a backfill reconstruction composition, which is characterized in that the composition comprises aeolian sand, loess, clay and fly ash, and the mass ratio of the aeolian sand to the loess to the clay to the fly ash is (1-3): (1-3): (1-3): (1-3), including endpoint values. The invention further relates to a method for preparing the backfill reconstruction composition and application of the backfill reconstruction composition in backfilling ground fractures. The backfill reconstruction composition can be used for backfilling a large number of ground cracks generated by mining, large-scale utilization of the fly ash is realized, and the water retention performance of soil in a mining area is improved, so that the social benefits and economic benefits of waste treatment and ecological environment restoration are achieved.
本发明涉及回填重构组合物、其制备方法和其在地裂缝精细回填中的应用。具体地，本发明涉及一种回填重构组合物，其特征在于，所述组合物包含风积沙、黄土、黏土和粉煤灰，并且所述风积沙、所述黄土、所述黏土和所述粉煤灰的质量比为(1～3):(1～3):(1～3):(1～3)，包括端点值。还涉及制备回填重构组合物的方法，以及回填重构组合物在回填地裂缝中的应用。本发明的回填重构组合物可以对因开采产生的大量地裂缝进行回填，实现粉煤灰的大量利用，改良了矿区土壤的持水性能，从而达到治废和修复生态环境的社会效益和经济效益。
