Abstract

The invention discloses a blasting cartridge connecting structure for mine deep hole blasting, which comprises a hinge shaft, a first sub-connecting part and a second sub-connecting part, the outer wall of the hinge shaft is hinged with the first sub-connecting part, and the outer wall of the hinge shaft on one side of the first sub-connecting part is hinged with the second sub-connecting part; fixing grooves are formed in the inner side of the first sub-connecting part and the inner side of the second sub-connecting part, directional protruding blocks are arranged on the inner side of the second sub-connecting part and the inner side of the first sub-connecting part, mounting blocks are mounted at the bottom end of the second sub-connecting part and the bottom end of the first sub-connecting part, and first threaded grooves are formed in the mounting blocks; a fixing mechanism used for fixing the position between the mounting blocks is arranged in the first threaded groove. By adopting the technical scheme, the blasting cartridge bodies are fixed between the first sub-connecting part and the second sub-connecting part, so that the two mutually connected blasting cartridge bodies cannot rotate relatively when being inserted into the blasting hole.

Description

technical field [0001] The invention belongs to the field of mine blasting devices, and more specifically, the invention relates to a blasting barrel connection structure for mine deep hole blasting. Background technique [0002] Blasting is a common method for mines to release ore bodies and broken rock masses. In drilling blasting, blasting with a hole depth of more than 5m is generally called deep hole blasting. Blasting is carried out by pre-cracking the top coal and roof in advance. It is the main means of pre-weakening of roof strata. [0003] However, in coal mine deep hole blasting, multiple blasting cylinders need to be inserted into the blasting hole before blasting, and during the process of inserting the blasting cylinder into the blasting hole, the blasting cylinder will rotate, so that the directional hole on the blasting cylinder cannot face the predetermined blasting position. As a result, blasting cannot be carried out according to the predetermined plan, ...
