METHOD FOR FILLING WELL CHARGES

摘要

A method for stemming blast holes includes drilling blast holes, tamping those with explosive, placement of boosters in the charge and mounting the explosive charge initiation system, filling the upper part of the hole with stem. While drilling holes one forms on the surface of the block a pile of drill sludge that before hole tamping is brought to flowing state. Then one fills the hole with explosive, with placement of boosters and mounting the explosive charge initiation system. After that drill sludge as stem is displaced to the hole with placement over explosive to the level of the block surface with initiation of blast hole.
