Open pit smooth blasting powder charging device and operation method of open pit smooth blasting powder charging device

Abstract

The invention belongs to the technical field of blasting powder charging, and particularly relates to an open pit smooth blasting powder charging device and an operation method of the open pit smooth blasting powder charging device. The open pit smooth blasting powder charging device is composed of a powder bag clamping and fixing device and a powder charging device body. The powder bag clamping and fixing device is composed of a semicircle clamping tube, a semicircle top plate, a semicircle base plate and a self-locking type binding strip. The powder charging device body is composed of a slant plate, a foot base plate, a perpendicular semicircle sleeve, a stabilizing plate, a bottom stopping rod, a top stopping rod, a reel, a brake wheel, a brake belt, a foot brake plate, a pawl wheel, a hand brake handle and a rope. The open pit smooth blasting powder charging device is simple in structure, practical and convenient to use, the powder bag manufacturing process and the powder charging process are combined together, the number of operators is decreased, and the labor efficiency is greatly improved. According to the open pit smooth blasting powder charging device and the operation method, the phenomena of powder bunch (powder tube) packaging material damage and detonating fuse kinking in the powder charging process are further avoided, and the powder charging quality of blast holes can be improved. The open pit smooth blasting powder charging device and the operation method are suitable for popularization and application in surface mines.

Description

technical field [0001] The invention belongs to the technical field of explosive charging in open pits, and in particular relates to a charge device for smooth surface blasting in open pits and an operating method thereof. Background technique [0002] At present, the known smooth surface blasting in the open pit often adopts uncoupled charge, and two methods are used for the processing of the charge package: one method is to fill the explosive in a hard plastic tube with a certain diameter for continuous charge, and put a tube in the whole tube. Detonating cord, the detonating cord is generally 1.0 meters longer than the hole; another way is to tie the charge roll and the detonating cord together and then tie them on the bamboo slices to form a charge string. When charging and stuffing, manual charging is used, and many people need to lift the processed medicine string gently, and slowly put it into the hole, so that the side with the bamboo slices is against the side of th...

Problems solved by technology

However, this process separates the processing of the drug pack from the charging of the drug. Especially when charging the drug, many people are required to participate in gently lifting the processed drug string and slowly putting it into the hole. This process is prone to drug leakage. The string (drug tube) collides and rubs against the wall of the blasthole, causing damage to the wrapping material of the gun string (drug tube) and kink of the detonating cord
