金属矿业的矿山公害预防措施同一般产业的公害预防措施不同,矿山停产后仍具有必须处理从采空区或堆积场流出的污染水以及必须半永久性地管理在探矿、采矿、选矿和冶炼过程中排出的废石、矿泥和冶炼废渣等特殊问题。因此,若想切实地预防矿山公害,就必须从长远观点来开发有效而经济的技术。根据这一观点,金属矿业事业团目前正通过多 Mine Metal Mines Preventing Pollution Unlike the prevention of pollution in the general industry, mines still have the potential to deal with polluted water flowing out of goafs or stubs and must be semi-permanently managed during prospecting, mining, beneficiation and smelting processes Discharge of waste rock, sludge and smelting slag and other special problems. Therefore, in order to prevent mine pollution effectively, it is necessary to develop effective and economical technologies in the long run. According to this view, the metal mining group is currently passing more
