摘要
我国是世界上第一产煤大国,煤炭在我国能源生产中占重要地位。随着国民经济的发展,对煤炭的需求量将越来越大。 但是,地下煤炭资源采出后,破坏了原有的地质平衡条件,引起采空区上方发生不同程度的塌陷,这种由于人们采煤活动引起的塌陷越来越被人们所认识。本文针对东北煤田生产的特点,对采煤塌陷的危害进行分析与论述,并提出对塌陷区形成的预测方法和治理塌陷的科学途径。
China is the largest coal mining country in the world. With the rapid economic deve lopment.the needs for coal in China is getting more and more. On the other hand,the collapses in coal mines are becoming more serious as a result of the changes of geological environment after coal mining. Fortunately, the hazard is being noticed in China. The damage of the collapses in northeastern China is described in the paper. And the ways for prediction and control the collapses in the area are presented.
