摘要
本文介绍了采矿设计中确定陷落角的各种不同方法。在此基础上提出在计算陷落角的设计步骤中应考虑破坏类型对陷落角的影响 ,进而根据破坏形式采用相应的计算方法。以板石沟铁矿上青矿区西端岩移问题为例进行了分析计算。
Different methods for determinating subsidence angle in mining design are introduced.Based on this,conditions about influence on subsidence angle for design steps are considered.Therefore the correspondimg calculatian method is used according to the failure type.Analysis and calculation are illustrated by the specific example of ground surface movement at the west Shangqing mining field.
