| Abstract: | There continues to be a problem of that the large input for small cutput.The main cause is that the explosive energy and the prime free surface are not utlized fully.Only making full use of the explosive energy and the prime free surface by strengthening the plug in blast holes and determining the line of least resistance suitably,can solve this problem. |
