Open publisher page 4 citations

Abstract

The top coal blasting technique is systematically studied and used in full mechanized caving working face 8911 of Xinzhouyao Mine of Datong Mining Administration.According to the research of fractal geometry and indoor blasting experiment,the triangle blasting hole scheme has the advantages of high energy utilization ratio and good blasting results. It is practically proved that the scheme can meet the need of the production in full mechanized caving method in hard coal seam.
