| 摘 要： | 采动损害是指由于地下采动在地表产生的开裂、沉降和塌陷等严重损害地表生态环境的地质灾害。在构造介质、构造界面特征相似,开采强度也相同的条件下,煤矿区采动损害与其所处的构造应力场性质有关。在构造挤压区,一定的地下开采强度可能不会对地表造成强烈损害;而在构造伸展区,同样强度的地下开采则可能对地表生态环境造成严重破坏。

| Abstract: | Underground mining-induced ground damage in coal mining area is a kind of geological hazard, including ground fissure, subsidence, collapse and so on, with the result of damaging ecological environment. Under the same conditions of structural-material complex, fracture system, and mining scale, the ground damage degree is related to the tectonic stress field. In compression tectonic region, certain underground mining scale may not result in severe damage of the ground, thereas in tension tectionic region the same underground mining scale may induce severe consequence in the ground. |
