丰羽矿是坑内开采,现有是矿山开采能力为33,000吨/月,组织生产。采矿方法以分段采矿法为主。 节能是当今社会的要求,对丰羽矿来说,也是降低成本的重要课题。采矿部门的耗能结构中电费占总能源费的99.9％,因此,以降低电力消耗为生产上的课题之一,不断采取各种措施。该矿的一个明显特征是由于围岩温度高而产生的坑内温度高。所以,为降低坑内温度所需的通风设 Feng Yu Mine is pit mining, the existing mining capacity of 33,000 tons / month, the organization of production. Mining methods to sub-mining law based. Energy saving is a requirement of today’s society. For Feng Yu Mine, it is also an important issue to reduce costs. In the energy structure of the mining sector, electricity costs account for 99.9% of the total energy costs. Therefore, various measures have been taken to reduce electricity consumption as one of the production issues. One of the obvious features of the mine is the high pit temperature due to the high surrounding rock temperature. Therefore, to reduce the temperature of the pit required ventilation
