一、目前各鑛贫化率和损失率高的基本原因到目前为止东北区所有鑛山,在开采过程中鑛石的贫化率和损失率是很高的,根据各鑛实际情况,贫化率和损失率高有下列几个主要原因:(一)地质测量工作薄弱在地质工作上,特别表现在鑛体轮廓复杂时,不能给设计人员提供准确资料,更由于采场试料工作不及时,不能进行素描或采取试样和及时圈定鑛体范围。其次,测量工作在采掘过程中的监督与验收,跟不上去。因此这都是造成贫化率和损失率大的原因。
I. At present, the basic reasons for the high rate of depletion and loss in various mines So far, all mines in Northeast China have a very high rate of depletion and loss of ore during the mining process. According to the actual situation of each mine, depletion There are several main reasons for the high rate and loss rate: (1) Weak geologic survey work In geological work, especially when the outline of the orebody is complicated, it can not provide accurate data to the designers. In addition, because the work of the stope sample is not timely , Can not be sketched or take samples and timely delineation of ore body range. Second, the monitoring work in the mining process supervision and acceptance, keep up. Therefore, this is the reason for the high rate of dilution and loss.
