我国金属矿山二次破碎工作量较大,且多采用打眼放炮方法,粉尘浓度高、劳动强度大、火药消耗量大、事故较多,以致影响矿山正常生产,甚至影响选厂能力的充分发挥。因此,寻求一种新的二次破碎方法是当前迫切需要解决的问题。高频电力破矿法,具有无粉尘、无飞石、可与采场各种设备同时工作、劳动强度小、操作简便、安全、比较经济等优点,是当前国外正在深入研究的新技术之一。
In our country, the secondary crushing workload of metal mines is large, and many methods such as drilling and blasting are adopted. The dust concentration is high, the labor intensity is large, the consumption of gunpowder is large, accidents are more, so that the normal production of mines is affected and even the full selection of plant selection is affected. Therefore, to find a new method of secondary crushing is an urgent problem to be solved. It is one of the new technologies currently under study in China that the high-frequency power mining method has the advantages of no dust, no fly stone, simultaneous work with various equipment in the stope, small labor intensity, easy operation, safety and economy .
