摘要
煤矿采空塌陷是山西省地质灾害的主要灾种.采空塌陷的发育程度由内因、外因共同决定.自然地理地质环境背景条件为内因,人类工程活动为外因.内因决定了采空塌陷的分布区域,外因则控制它的发育程度.内因通过外因表现出来.
Collapse of mined out area in coal mines is the chief geologic disaster in Shanxi Province.The developing level for collapse of mined out area depends on internal and external causes.The internal causes include the background conditions of geography and geological environment.The external causes come from human engineering activities.Internal causes decide the distribution of the collapse of mined out area,while external causes control its developing level.
