A kind of chute suspension blasting device and its applied chute clogging and dredging method

Abstract

The invention discloses a sliding well suspension blasting device and application of a sliding well blocking dredging method. The device comprises a lifting transport platform for fixing an explosive package, and an air compressor for controlling the lifting transport platform to suspend and launch, wherein downward air outlets are evenly distributed at the periphery of the bottom of a lifting transport platform, the air compressor communicates with the air outlets on the lifting transport platform through gas transmission soft tubes, and the gas transmission soft tubes are freely expandable and foldable cloth soft tubes; and a telescopic landing field for placing the lifting transport platform is arranged below a blocking material, the telescopic landing field is fixed to the edge of the sliding well contact path below the blocking material by a telescopic mechanism. According to the sliding well suspension blasting device and the application of the sliding well blocking dredging method, a jet type blasting device is utilized, the explosive package is transported below the blocking material of the sliding well through the high pressure airflow generated by the air compressor, the fixed point suspension is maintained, the blocking material is blasted and dredged through the effective blasting at close range, and the sliding well high level blocking can be effectively solved; and the sliding well suspension blasting device and the application of the sliding well blocking dredging method has the advantages of simpleness, convenience and practicability, and safety and reliability, and the sliding well suspension blasting device and application of the sliding well blocking dredging method can be widely promoted and applied.

Description

technical field [0001] The invention relates to a technique for treating high-level blockage of a chute by blasting, in particular to a suspension blasting device and method for a chute. Background technique [0002] The chute is a transfer system for ore and waste rock in mine production. During the production process, due to the rough wall of the chute, mineral accumulation and the existence of large ore, etc., the chute will be blocked at a high level, seriously affecting the normal production of the mine, and it is easy to handle it improperly. Threat to the safety of workers. [0003] The traditional way of dredging the chute is mainly water flushing to dredge the chute and blasting. [0004] The water flushing dredging method reduces the friction of the blockage by injecting water into the chute, so that the blockage falls and the chute is dredged. However, in the way of dredging by water flushing, the water volume is too large and difficult to control, which is like...
