Abstract
The trial test results for down-the-hole electric detonation cord with electronic delay are presented. The analysis is performed for various designs of charges with electronic detonation cords. Based on the commercial testing, the rational design of a divided down-the-hole charge with electronic detonation cords has been developed.
