The Mechanism and Prediction Technique of Induce Shock Bump by Goaf Cover Terrane
Based on cases of caving disaster in widespread goaf and the comprehensive analysis of document materials, the paper presents a discussion of a special coalrock dynamic disaster phenomenon in appearing recent years, that is the shock bump and gas dynamic disaster induced by caving disaster in widespread goaf. The paper demonstrates kinetic evolution and special temporal scale in the previous period of shock bump and reveals exhaustively the characterization of shock bump in goaf and the spatial temporal scale composed by the dynamic disaster. Focusing on the development and the formation of shock bump, the technology of AE monitoring can be viewed as the basic way to predict the shock bump, and the linear location and arbitrary triangle location can be considered as the basic principle of source location.
