我国的能源结构是以煤炭为主,约占70％左右,在近期内不会有太大的变化,这就要求我们在重视煤炭开发工作的同时,也要注意研究如何充分合理地利用煤炭资源,使它科学地、有效地、无害地为社会发展服务。 解放以来,我国煤炭工业的发展极为迅速,1949年生产煤炭为3243万吨,1994年生产了11亿吨左右,提高了30多倍,取得的成绩惊人,对社会的贡献巨大。但同时也带来了一些不可忽视的后果,例如,煤炭资源的回采率太低,据统计:目前我国约有200亿吨左右的煤炭资源被遗弃在井下;在开采与燃烧时严重污染了人类的环境,如矿井污水外排污染了地表水,煤开石、CO_2、烟尘、硫化物污染了空气形成
The energy structure of our country is dominated by coal, accounting for about 70%, and there will not be much change in the near future. This requires us to pay attention to how to make full and reasonable use of coal resources So that it serves the development of society scientifically, effectively and harmlessly. Since the liberation, the development of China’s coal industry has been extremely rapid. In 1949, the coal production was 32.43 million tons, about 1.1 billion tons was produced in 1994, an increase of more than 30 times. Amazing results have been achieved and enormous contributions have been made to the society. For example, the recovery rate of coal resources is too low. According to statistics, at present, about 20 billion tons of coal resources in China are abandoned in the well. In the process of mining and burning, it has seriously polluted the human beings Of the environment, such as mine effluent polluting the surface water, coal, stone, CO 2, soot, sulfide pollution of the air form
