Relation between Surrounding Rock Displacement and its Size of Shaft on its Self-Weight Body Force Condition

Abstract:

We derived the relation between surrounding rock displacement of shaft prototype and that of model on its body force condition of self-weight based on the similarity theory. According to the results of discussion of the equation, we derived dimensional expression of surrounding rock displacement of shaft. And we analyzed the relation between displacement and diameter(d) and cross-sectional depth(h) by numerical methods.
