采煤和坑口发电,留下了一个个塌陷区,一座座歼石山和一堆堆煤灰,污染了环境,毁坏了耕地。近几年,安徽淮北矿区较大规模地进行了塌陷区造地复田综合治理,以及用电厂粉煤灰充填塌陷区试验研究取得成功,为我国的国土整治提供了一些有益的启示。 煤炭是我国的主要能源。1986 Coal mining and pit power generation left behind a series of subsidence areas, a seated rocky hill and a pile of coal ash, which polluted the environment and destroyed cultivated land.
