Abstract

The invention discloses an ultrahigh water filling material. The ultrahigh water filling material consists of a component A and a component B, wherein the component A comprises calcium sulphoaluminate, calcium aluminate, calcium carbonate, sodium carbonate, polyacrylamide and sodium carboxymethyl cellulose; the component B comprises calcium sulfate, calcium oxide, meta-aluminate and calcium chloride; and the meta-aluminate in the component B is sodium meta-aluminate or calcium meta-aluminate. In the ultrahigh water filling material, the component A comprises 45 to 75wt% of calcium sulphoaluminate, 15 to 45wt% of calcium aluminate, 2 to 8wt% of calcium carbonate, 2 to 8wt% of sodium carbonate, 0.5 to 2wt% of polyacrylamide and 0.5 to 2wt% of sodium carboxymethyl cellulose, the component B comprises 70 to 90wt% of calcium sulfate, 8 to 25wt% of calcium oxide, 1 to 5wt% of meta-aluminate and 1 to 3wt% of calcium chloride, and the weight ratio of the component A to the component B is (0.5-2):1. The ultrahigh water filling material provided by the invention has the advantages of short initial setting time and high and stable strength after condensation. The ultrahigh water filling material provided by the invention is non-toxic, odorless, pollution-free, safe and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of mine filling, in particular to an ultra-high water filling material. Background technique [0002] High-water materials are cementing materials for unit filling of gold ore, iron ore, tailings filling, and waste filling in the metallurgical industry. It can be widely used in coal industry roadside filling support, goaf plugging and fire extinguishing, flame retardant, well wall thickness filling support, etc. [0003] High-water materials used for goaf filling have the advantages of simple process, fast condensation speed, and stable performance. In order to reduce the deformation of surface buildings and structures caused by mining, the goaf of mining engineering generally needs to be supported or filled. There are two main types of traditional filling materials: one is filling materials such as Portland cement mixed with water glass, etc. However, the service life of this type of material is short (us...
