Research on Optimization of Blasting Parameters in Piaotang Tungsten Mine
In order to adapt to the problems of uneven blasting block size and large block rate caused by equipment updates and geological conditions changes in the Piaotang tungsten mine,combined with Livingston blasting theory,single hole blasting funnel test and multi hole same section blasting funnel test were carried out on site,and the optimal burial depth of the explosive package,optimal blasting funnel volume,optimal hole spacing,and optimal resistance line parameters of the Piaotang tungsten mine were obtained.And it was determined that the optimal hole spacing for the Piaotang tungsten mine is 1.0m～1.24m,and the explosive consumption is 0.60～0.73kg/t.This provides a theoretical basis for reducing the rate of large blasting blocks and reducing mining costs.
