摘要
通过系统分析井工开采地表损害特征、裂缝开裂与闭合机理、影响地表损害的地质采矿条件和时间等主要因素,给出了评价这种损害的基本指标和损害程度的分类方法,对从事该领域研究工作人员具有一定的借鉴意义。
The paper systematically analyzed the main factors of surface damage characteristics of underground mining,mechanism of fracture cracking and closing and geological and mining conditions,and proposed the basic indexes of damage evaluation and classification method of damage degree. The result has a certain reference significance to researchers in this field.
