力确保南非金矿开采业的长期稳定发展,在面临利润下降的情况下,必须采用更为有利的开采作业方法。新技术开发的重点应放在采场的回采作业。据了解,主要制约采场生产能力的作业工序是采用爆破法破碎岩石。尽管爆破是一种有效的方法,但是它也给后继工序带来许多困难和限制,如矿石搬运和迫使回采作业按序循环等。 To ensure the long-term and stable development of South Africa’s gold mining industry, in the face of declining profits, a more favorable mining operation must be adopted. The focus of new technology development should be placed on stope mining operations. It is understood that the main constraints of the production capacity of stope operations procedures is the use of blasting broken rock. Although blasting is an effective method, it also poses many difficulties and constraints to follow-up processes, such as ore handling and the forced circulation of recovery operations.
