山坡露天矿在选用主平巷溜井运输的开拓方式后,由于受到松散介质(主要指崩落矿岩)的物理力学性质和资金状况的影响,放矿往往达不到理想的效果,从而给安全、生产带来问题,直接降低企业经济效益。近年来,振动放矿技术得到迅速发展,振动放矿理论的研究和振动放矿机的研制也取得了很大进展。但振动放矿应用于主溜井尚不多,因而对这个问题作些探讨是很有必要的,对振动放矿技术系列化的理论和实践也是一个补充。主溜井的特性与振动放矿机设计的关系主溜井的特性是设计、计算、选取振动放矿机有关技术参数的重要依据。1.主溜井服务年限长
Due to the physical and mechanical properties of loose media (mainly cofferdams) and the financial status of opencast slopes, the ore drafting often fails to achieve the desired results after selecting the open way of main-lane sloping transportation. Therefore, Production problems, directly reduce the economic efficiency of enterprises. In recent years, vibrating ore drawing technology has been developed rapidly, vibrating ore leaching theory research and development of vibrating ore muller has made great progress. However, there are not many applications for vibration ore leaching in the main slide. Therefore, it is necessary to discuss this issue, which is also a supplement to the theory and practice of series technology of vibration ore leaching. The relationship between the characteristics of the main slide and the design of vibrating ore miner The characteristics of the main slide is an important basis for the design, calculation, selection of the relevant technical parameters of vibrating ore miner. 1.
