Study on Presplitting Blasting the Roof Strata of Adjacent Roadway to Control Roadway Deformation

In order to solve the problem of roadway deformation based on the theory of “short cantilever beam by roof cutting,” the method of “pressure relief by roof cutting in the adjacent roadway” is proposed. Through presplitting blasting the roadway hard rock layer, the stress propagation path is cut off,...
