目前,国内外的有色金属矿山,其开采有向深部发展和由开采氧化矿逐步向开采硫化矿方面过渡的趋势,因而硫化矿开采时产生的自燃发火及自爆现象将给这类矿山带来了巨大困难,甚至带来巨大危害。例如火灾危害、坑内的高温高热及烟雾、粉尘爆燃,矿石的运输贮存困难,炸药的不安定性及矿石的变质和损失等等,西方采矿专家认为:即使在现在虽然采矿作业中已改进了矿石运搬的控制及加强了安全防护,但由于世界采
At present, non-ferrous metal mines both at home and abroad have a trend of deep development and gradual transition from mining oxide ore to sulfide ore mining, and spontaneous combustion and self-explosion generated during the mining of sulfide ore will bring such mining Huge difficulties, even great harm. Such as fire hazards, high temperature and heat in the pit and smoke, dust deflagration, ore transportation and storage difficulties, the instability of explosives and the deterioration and loss of ore, etc. Western mining experts believe that even though mining operations have improved ore transportation Move control and enhanced security, but because of the world mining
