在矿床的地下法开采中,制备胶结充填料的水泥消耗量已达300万吨/年,年增长速度为7～10％,现已发现有许多种再生材料可作水泥的代用品。在有色矿山胶结充填量已占总充填量的90％。新设计的矿山主要是
In the underground mining of the deposit, the amount of cement used to make cements is up to 3 million tons / year at an annual rate of 7-10%. Many types of recycled materials have been found to be candidates for cement. Cementing in non-ferrous mines has accounted for 90% of the total filling amount. The newly designed mine is mainly
