Abstract

The invention relates to the technical field of blasting charging, and particularly discloses a medium-length hole charging and returned powder recycling device for blasting. The medium-length hole charging and returned powder recycling device for blasting comprises a positioning ring and a PLC, wherein the positioning ring can be placed in a blasting hole, an air guide ring is arranged inside the positioning ring, an air pump communicates with the air guide ring, a plurality of clamping pistons communicating with the air guide ring are arranged on the positioning ring, a recycling bag is arranged on the positioning ring, a limiting sleeve is arranged inside the recycling bag in a penetrating mode, a feeding pipe is slidably arranged inside the limiting sleeve, a compaction base is arranged at the end, located inside the blasting hole, of the feeding pipe, an air inlet pipe is arranged on the outer wall of the feeding pipe, a plurality of compaction air cylinders communicating with the air inlet pipe are arranged on the compaction base, the air inlet pipe communicates with the air pump, the compaction air cylinders and the air pump are both electrically connected with the PLC, and the working ends of the compaction air cylinders penetrate through the compaction base and are fixedly connected with auxiliary compaction plates. The medium-length hole charging and returned powder recycling device aims to solve the problem that when explosives are placed in a blasting hole in traditional mining blasting, the explosives are not recycled when falling out of the blasting hole.

Description

technical field [0001] The application relates to the technical field of blasting charge, and specifically discloses a medium-deep-hole charge return powder recovery device for blasting. Background technique [0002] The mining industry refers to the mining of naturally occurring minerals such as solids (such as coal and minerals), liquids (such as crude oil) or gases (such as natural gas). During the mining process, if a relatively hard rock environment is encountered, in order to maintain mining work. Blasting operations are often required to carry out or expand the mining operation area normally. [0003] Blasting is a technology that uses the compression, loosening, destruction, throwing and killing effects of explosives in air, water, earth and rock media or objects to achieve the intended purpose. When the explosive package or charge explodes in the earth-rock medium or structure, the earth-rock medium or structure will be compressed, deformed, destroyed, loosened and...
