CN105314944A 一种矿用复合水泥胶结料及矿用充填材料 无效 - 驳回

一种矿用复合水泥胶结料及矿用充填材料
摘要：
本发明涉及采空区充填领域，具体公开了一种矿用复合水泥胶结料及矿用充填材料。所述胶结料按重量份计，包括如下组分：复合硅酸盐水泥75～92份、硫铝酸盐水泥5～15份和石膏3～10份。所述矿用充填材料以所述胶结料掺加粉煤灰和/或煤矸石制成。本发明制备矿用复合水泥胶结料所用的原材料来源广泛、价格低廉，制备得到的胶结料凝结时间和抗压强度可调，与煤矸石、粉煤灰混合配制成的矿用充填材料，可以满足长距离泵送要求，能够满足不同井下充填工程的需要。
摘要（英）：

The invention relates to the field of goaf filling, in particular to a mining composite cementing material and a mining filling material. The cementing material is prepared from, by weight, 75-92 parts of composite portland cement, 5-15 parts of sulphate aluminium cement and 3-10 parts of gypsum. The mining filling material is prepared from the cementing material, coal ash and/or coal gangue. The raw materials for making the mining composite cementing material are wide in resource and low in cost, the prepared cementing material is adjustable in coagulation time and compressive strength, and the mining filling material prepared from the mining composite cementing material, the coal gangue and the coal ash in a mixed mode can meet the requirement for long-distance pumping and can meet the requirements of different kinds of underground filling engineering.
