QIU Jing-cheng (Dept of Land and Natural Resources,KunmingUniversity of Science and Technology, Kunming 650093, China)
During the explosion implementation in Longshan dolomite mine, the geological conditions changed, dissolved caves and troughs appeared, which would affect the effect of explosions directly. Some measures were taken according to the actual situation, such as different stuffing, changing the position of explosive chamber, changing explosive-filling structure and so on, which eventually guaranteed the effect and safety of explosions.
