Abstract:
Abstract:Using sensitised emulsion explosive technique in JianGou hard top coal imply Middle-long hole blasting and weakening of top coal. The results show site sensitised emulsion explosive technique achieving good results in JianGou coal, we monitor to top coal fractured and the roof、the floor and the two sides deformation monitoring, then description of the blasting process and selecting of blasting parameters.
Key words: Key words：Emulsion explosive, Middle-long hole blasting, steep seam, large section mining
