| Abstract: | In this paper, the calculation of blasting parameters under the condition of only using general ammonium nitrate explosive cartridges with a diameter of 32mm for smooth blasting was discussed on the basis of briefly stating the mechanism of smooth blasting. Through an engineering example, the application of the calculating method of blasting parameters was introduced. In addition, author's understanding and experience of how to well use smooth blasting technology were expounded and a proposal for test of water pressure smooth blasting was put forward. |
