A Remodeling Material And Its Method For The Water-Resisting Layer Of An Internal Waste Dump In An Open-Pit Mine

ADstracy A remodeling material and its method for the water-resisting layer of an internal waste dump in an open-pit mine, which is suitable for the field of water resources protection in coal mining. The remodeling material is mudstone geopolymer, which comprises: water, gel material, activator and standard sand. The method comprises the following steps: Determine the material ratio of the remodeling water-resisting layer according to the actual conditions; compact the surface of the waste dump, build the molds, evenly pour the remodeling materials, vibrate and trowel; cure for a period of time, and complete the remodeling of the water-resisting layer at this stage. Complete the remodeling of the whole water-resisting layer according to this process cycle. The invention has simple construction and low cost, can complete the remodeling of the water-resisting layer of an internal waste dump in an open-pit mine, realize ecological reclamation, and is of great significance to the construction of green mining mine. drawings o 1escripions 1 om 4 Figure 1
