Abstract

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.
