DEVICE AND METHOD FOR CHARGING POWDER AND GRANULAR EXPLOSIVES

摘要

PROBLEM TO BE SOLVED: To provide a device for charging powder and granular explosives capable of reducing a burden on workers in charging operation by a simple device structure and securely and remarkably shortening working time. SOLUTION: This device 10 for charging powder and granular explosives used for charging the powder and granular explosives in a blast hole 1 comprises an inlet opening part 31 for throwing the powder and granular explosives P therein and an outflow port 34 opened to the lowest position and flowing out the powder and granular explosives P. The device also comprises a storage container 30 having a bottom surface part at least a part of which is formed in a tilted surface 36 to lead the total amount of the stored powder and granular explosives P to the outflow port 34 by gravity and having a valve element 35 installed at the outflow port 34 so that an opening can be adjusted from a fully closed position to a fully open position and a carrying vehicle 20 carrying the storage container 30 mounted thereon.
