    • Abstract
  • Aiming at the violent strata behaviors during mining period of working face and phenomena that brackets and loaders are pressed and the cable drain line is damaged many times, the roof blasting presplitting technology is implemented, which effectively weakens the strength of pressure and effectively improves the face safety production outlook, and the effect is obvious. The optimized blasting charge process is simple and fast construction.
