Abstract

In order to study the stability influence of abandoned stope on existing surface constructions, this paper summarizes and analyzes the main controlling factors based upon one mine in Hebei province. This paper also details a qualitative and quantitative analysis utilizing the “Three Zones Theory”and“Movement Zone of Rock Theory”. The results indicate that: a) Based on the “Three Zones Theory”, a qualitative conclusion could be made that the empty stope area would result in surface deformation in certain range, b) Based on the “Movement Zone of Rock Theory”, the safety of surface constructions would be affected, thus the empty stope should be treated in time. The paper has validated the feasibility of a proposed comprehensive analysis method on the stability influence of the abandoned stope on the existing surface constructions, and it also provides a scien-tific basis of emphasizing the necessity of treating the empty stope.
