| Abstract: | in view of the very thin coal seam mining under the condition of unstable false roof, traditional supporting false guns taken easily induced roof accident; Pick the top guns taken lead to high mixed rate of coal and gangue, choose strength of coal and gangue, coal quality is poor, the low comprehensive benefits. In this paper, based on the analysis of false roof mining roof stability, can used in directional fracture blasting theory, first proposed false guns taken together to directional breaking controlled mechanism, combined with the actual to the fracture form and process parameters. Through industrial test to obtain good economic and technical effect, can be used widely in similar working face. |
