Abstract: The goaf has become one of the most important hazard sources affecting the production safety of mines in China.While dealing with the goafs, the residual mineral resources around the mined area should be recovered as far as possible.Because of the long exposure and concentrated stress, the mined area and the surrounding rock are often damaged.It is difficult to control the blasting effect for the large and variable resistance line of goaf.To solve the problems, bundle-hole meticulous blasting technology is introduced.In order to achieve good blasting effect, this technology determines the number of holes according to the maximum resistance line within the blasting range, and adjusts the number of charges according to the change of each part’s resistance line.This technology makes the blasting energy evenly distributed in the blasting scope, which not only guarantees the fragmentation effect, but also makes full use of the explosive energy.
