| Abstract: | The experiments and its application of wide-space small burden compression millisecond blasting in the exploitation of stone by excavating in underground factory house at the right blank of the Three Gorges Project are described. The multiple blasting experiments and optimization of drilling blasting parameters were adopted to not only remarkably increase the blasting effectivenes and noticably lower the cost of engineering, but also optimize the mined rock size. |
