在开采矿床的过程中,常使用大量的混凝土、砂—砾石—粘土混合料、由各种溶液胶结的干料、胶结充填料等等。“胶结充填料”可以认为是由活性及钝性胶结剂和隋性物料以不同的重量比组成的一种合成物。活性粘结剂的加入是使钝性胶结剂(如磨碎的粒状高炉炉渣)活化并加速其周化。在采矿工艺中使用这些材料已成为回采作业程序的一个有机组成部分。然而, In mining the process, often use a lot of concrete, sand - gravel - clay mixture, by a variety of solution-cemented dry material, cemented filling material and so on. A “cementitious filler” can be considered as a composition of active and passive cement and inert materials in different weight ratios. The addition of an activated binder activates and accelerates blunt cements, such as ground granulated blast furnace slag. The use of these materials in mining processes has become an integral part of the recovery operations. however,
