为了提高有用矿物的回收率,在许多情况下需要广泛采用胶结充填料。从便于输送充填料和达到其额定强度的观点出发,选择胶结充填料的最优配比是至关重要的问题。通常采用建筑工业使用的确定混凝土配比的计算试验法,或是根据充填料的特点,对计算试验法的数据进行修正。上述方法的主要缺点是,当采矿技术条件或者输送距离变化时,不能及时地改变充填料的配比。在这些
In order to increase the recovery rate of useful minerals, it is necessary in many cases to widely use cemented fillers. From the point of view of facilitating the feeding of the filling material and achieving its rated strength, it is of crucial importance to select the optimal ratio of the cementing filler material. The calculation test method for determining the proportion of concrete used in the construction industry is usually adopted, or the data of the calculation test method is revised according to the characteristics of the filling material. The main disadvantage of the above method is that the filling material can not be changed in time when the technical conditions of mining or the conveying distance change. In these
