机械化综放采煤
1.
According to the surface surveying results obtained in recent five years,it is considered that the surface damage which is caused by using mechanized sublevel caving method under thick cappe depends largely on the volume of mining excavation,the mechanical properties of the capping rock,its occurrence and thickness.
根据五年来的地表观测结果,认为在推覆体下进行的机械化综放采煤造成的地表损害主要取决于开采空间及推覆体岩体的性质、赋存条件及其厚度。

综合采煤机械化
补充资料:综采放顶煤
综采放顶煤:厚煤层煤炭开采技术之一。把原来分层开采的煤炭,一次采完。方法是,在煤层底部按传统方法开采,使上面的煤炭在矿压的作用下,自动落下来。
