穆龙陶露天矿开采的金矿床位于沙漠地带。该矿露天坑容积现约7亿m~3,采深250m,而其设计深度为600m。该矿主要的大气污染源为汽车运输。其余的污染源(例如定期排放大量有害物质与粉尘的爆破作业)虽也重要,但终究为次要的。从整体上看,我们认为,露天矿大气的正常化问题属于环境问题的一部分,其中也包括人们的生活环境。 Mu Longtao open-pit mine gold deposits located in the desert zone. The open pit capacity of the mine is about 700 million m ~ 3, mining depth of 250m, while its design depth of 600m. The mine’s main source of atmospheric pollution is motor transport. The remaining sources of pollution, such as blasting operations that emit large quantities of hazardous substances and dust on a regular basis, are important, but ultimately secondary. On the whole, we believe that the normalization of the atmosphere in open-air mines is part of the environmental problems, including people’s living environment.
