Metal mine underground filling cementing material as well as preparation method and application thereof
The invention provides an underground filling cementing material for a metal mine. The underground filling cementing material is prepared from the following components in parts by weight: 70 to 80 parts of granulated blast furnace slag micro powder, 3.75 to 10 parts of cement clinker, 3.75 to 7.5 parts of quick lime, 10 to 20 parts of desulfurized gypsum, 1.25 to 2.5 parts of sodium carbonate and 1.25 to 2.5 parts of sodium sulfate. Polar molecules or ions generated after sodium carbonate, sodium sulfate and lime are dissolved in water are utilized to destroy structures such as silica tetrahedrons and alumina tetrahedrons of the slag, so that the slag is dispersed in a solvent, and then the slag generates gelling property under the co-excitation action of the lime, cement clinker and gypsum. The gelling agent can be well compatible with blast furnace slag powder and other materials in most regions of the country, and is convenient to use and high in capability of adjusting measures to local conditions. The invention further provides a preparation method and application of the metal mine underground filling cementing material.
本发明提供了一种金属矿山井下充填胶凝材料，包括以下重量份数的组分：粒化高炉矿渣微粉：70～80份，水泥熟料：3.75～10份，生石灰：3.75～7.5份，脱硫石膏：10～20份，碳酸钠：1.25～2.5份，硫酸钠：1.25～2.5份。本发明利用碳酸钠和硫酸钠以及石灰在水中溶解后所产生的极性分子或离子，破坏矿渣的硅氧四面体、铝氧四面体等结构，使矿渣分散和溶剂，然后再在石灰、水泥熟料和石膏的共同激发作用下，使其产生胶凝性。本发明中的胶凝剂能够较好的兼容全国大部分地区的高炉矿渣粉等其他材料，使用方便，因地制宜能力强。本发明还提供了一种金属矿山井下充填胶凝材料的制备方法及应用。
