Abstract

In the mining industry, significant progress and increased mineral production cause waste disposal issues which is one of the crucial problems in mining operations. It leads to both environmental and economic issues. Particularly, wastes from the production of metallic sulfide ore cause serious environmental pollution. In the last three decades, waste has been stored in underground openings in a controlled manner as paste-fill. Paste-fill is created by waste, water, and chemical additives. In this paper, two types of wastes were chosen to investigate the usability of tailings as paste-fill material. A lead and zinc underground mine was selected as a research site located in Balikesir, Turkey. First of all, several tests were conducted to analyze the physical, chemical, and mineralogical characteristics of paste-fill materials. Then, one of the design of experiment methods was used to create different mixtures of paste-fill specimens by changing the binder ratio and water content as input variables for four curing times. Finally, the strength properties were obtained as output variables, and an optimum mixture of paste-fill was determined. The results show that the tailings can be used as paste-fill material to achieve environmental and economic benefits and provide a safe working environment.

通过试验设计，对尾矿作为膏体充填材料进行试验研究

在采矿业中，矿物生产的显著进步和增加引起了废物处理问题，这是采矿作业中的关键问题之一。这会导致环境和经济问题。特别是金属硫化矿生产产生的废弃物对环境造成严重污染。在过去的三十年里，废物以一种受控的方式被储存在地下洞口，作为糊状填充物。糊状填料是由废物、水和化学添加剂制成的。本文选取两种废弃物，对尾砂作为膏体充填材料的可用性进行了研究。位于土耳其巴利克西尔的一个铅锌地下矿场被选为研究地点。首先，对膏体充填材料的物理、化学、矿物学特性进行了分析。然后，采用其中一种实验设计方法，通过改变胶凝比和含水率作为输入变量，在4次养护时间内形成不同的膏体-充填体试件混合体。最后以强度特性为输出变量，确定了膏体-填料的最佳配比。结果表明，该尾矿可作为膏体充填材料，具有良好的环境经济效益和安全的作业环境。
