最近几十年内,在苏联采矿工业中有用矿物露天开采的先进方法获得进一步推广应用,采掘与运输设备不断完善,采矿作业得到强化。但与此同时,有关大气正常化的实施措施尚不配套,因此造成了露天矿作业区有害杂质浓度超标的后果。今后的劳动条件正常化问题还将 In recent decades, advanced methods for the open pit mining of useful minerals in the mining industry in the Soviet Union have been further promoted and applied, mining and transportation equipment have been continuously improved, and mining operations strengthened. However, at the same time, the implementation measures for the normalization of the atmosphere are not yet implemented, resulting in the consequences of excessive concentrations of harmful impurities in the open pit operations. The normalization of labor conditions in the future will also be
