| Abstract: | Commercial test of loosen blasting technology for bottom floor rock in comprehensive mechanized coal face of Liuzhuang mine has been proceeded, which define the technology of water-axial uncoupled charge pattern and anti-detonation on E121105 working face. At the same time, design and optimization of blasting parameters (depth of borehole, charge of borehole, ultimate burden, density of borehole, stemming of borehole and so on) have been put forward, and good results has been got. |
