一、工矿区造成的恶果随着现代工业的飞速发展,世界各国对矿藏资源的需要量和开采量日益增加。据有关资料统计,全世界每年采掘的金属、非金属、煤炭、粘土、石材、砂砾等矿藏共约90亿吨,估计到本世纪末,矿石开采量至少提高到现有水平的3倍以上,才能满足全世界工业发展的需要。我国矿产资源丰富,已探明的矿产达100多种,其中储量为世界各国前列的金属矿产近20种。全国有各类主要露天矿山1,507个。随着国民经济建设的需要和开采技术的发展,采矿量也将日益增加。矿藏资源的开发利用,一方面给人类提供了各种物质能源,另一方面又不可避免地带来一系列问题。主要表现在以下几个方面:
First, the consequences of industrial and mining areas With the rapid development of modern industry, the world’s mineral resources on the demand and the amount of exploitation is increasing. According to relevant statistics, about 9 billion tons of mineral, non-metallic, coal, clay, stone, gravel and other minerals are extracted each year in the world. It is estimated that by the end of this century, the amount of ore mining will be raised to at least three times of the current level Meet the world’s industrial development needs. Our country is rich in mineral resources, and more than 100 kinds of proven minerals have been discovered. Among them, there are nearly 20 kinds of metal minerals in reserves in the world. There are 1,507 major open pit mines in the country. With the needs of the national economy and the development of mining technology, the amount of mining will also increase day by day. The development and utilization of mineral resources, on the one hand, provide human beings with all kinds of material and energy resources, on the other hand they inevitably bring about a series of problems. Mainly in the following areas:
