Any mining technique that allows improved extraction of ore from underground workings results in improved financial viability of the mining process concerned. Such improved extraction rates are being achieved by backfilling previously mined voids with cemented mine waste, which also improves stability of the underground workings. This research will further improve the financial viability of mines using this technique by reducing the amount of cement used, without compromising the safety of workers. In some otherwise marginal mines, these savings could be the difference between the mine staying open and being placed on care-and-maintenance, with the potential loss of jobs in mainly remote parts of the country.

任何采矿技术，只要能改进从地下工作中提取矿石的方法，就能提高有关采矿过程的财务可行性。这种提高的提取率是通过用胶结的矿山废物回填以前开采的空洞来实现的，这也提高了地下工作的稳定性。这项研究将通过减少水泥使用量，在不损害工人安全的情况下，进一步改善使用这种技术的矿山的财务可行性。在一些原本处于边缘地位的矿山，这些节省下来的钱可能是矿山继续开放还是被置于护理和维护状态的差别，而这可能导致该国主要偏远地区的工作岗位流失。
