目前,全世界的排土场和尾矿场约堆有16000亿米~3采出的岩石和选出的尾矿。另外,露天矿、排土场和尾矿场占着几万公顷耕地和造林用地。为了进行采掘而进行的矿床疏干,既破坏了半径数十公里范围内的地下水原有状态,又降低了地下水和地表水的质量。大气受各种来源含尘有机与无机排放物的污染,其中包括来自井下巷道、排土场、各种加工车间和加工厂等排放的废物。由于对生物圈的上述各方面的综合影响,植物的生长条件、动物的生存条件和人的生活条件都大大地恶化了。对矿物原料的需求不断增长,势必加
At present, about 1,600 billion m 3 of rock and tailings are collected in dumps and tailings all over the world. In addition, open-pit mines, dumps and tailings occupy tens of thousands of hectares of arable land and afforestation sites. Dredging deposits for excavation not only undermined the original state of groundwater within a radius of several tens kilometers but also reduced the quality of groundwater and surface water. The atmosphere is polluted by dusty organic and inorganic emissions from a variety of sources, including wastes from underground tunnels, dumps, various processing workshops and processing plants. Due to the combined effects of the above aspects of the biosphere, plant growth conditions, animal living conditions and human living conditions have greatly deteriorated. Demand for mineral raw materials is on the rise and is bound to increase
