Abstract：Abandoned stope disposal is a great problem of mining technology and production safety. In current, domestic and foreign methods disposing abandoned stope, it was expensive that they could solve the problem rockburst. In order to dispose a great deal of abandoned stope left behind in breast method and so on openstope method and extract out remnant mine economically and effectively, on the basis of domestic and foreign methods disposing and utilizing abandoned stope, local grooving top-caving and roof cutting and pillar dilapidation is proposed by controlled explosion in this paper. And their methods designing the basic parameters and analysing and evaluating the effective cutting roof are studied by numerical simulation, similarity simulation and Acoustic Emission (AE) techniques of rock-mass. In a word, a set of the method and actualizing and evaluating system is put forward that may be extended and used for reference. The integral method and actualizing and evaluating system includes analysis method, project design method, the method carrying out and monitoring and evaluating. The result shows that it is technologically feasible, economically reasonable and simple suitable, and it has the significant social significance and the important economic value.
