Strip mine blasting flying rock safety protection device and protection method

Abstract

The invention discloses a strip mine blasting flying stone safety protection device and a protection method, the strip mine blasting flying stone safety protection device comprises a rotating ball, a motor, a water pump and a cylinder, the rotating ball is pushed to rotate in a rotating groove, so that the inclination angle of a photovoltaic solar panel is adjusted, and the requirements for different inclination angles of the photovoltaic solar panel under different conditions are met; the motor rotates to drive the first threaded rod to rotate, so that the mounting plate is further driven to move on the first threaded rod, the plate body stretches out and draws back in the cylinder, the overall protection area is adjusted, and the requirements for different protection areas under different conditions are met; water in a water tank is fed into a water outlet box through a water guide pipe by utilizing a water pump and is further sprayed out through a spraying head, so that dust generated in the blasting process is subjected to spraying and dust falling, and an operator stands on the rear surfaces of the cylinder body and the plate body, so that safety protection on the operator is realized; and flying rocks generated in the blasting process are prevented from injuring operators.

Description

technical field [0001] The invention relates to the technical field of blasting in open-pit mines, in particular to a safety protection device and a protection method for blasting flying rocks in open-pit mines. Background technique [0002] The open-pit mine is to strip off the floating soil and surrounding rock covering the upper part of the ore body and its surroundings, transport the waste rock to the dump, and directly extract the ore from the open ore body. When the ore body is buried shallowly or there are outcrops on the surface, open-pit mining is superior to underground mining. The work of stripping away the upper soil is called stripping. The ratio of the amount of stripped rock and soil to the amount of mined ore is called the stripping ratio. If the stripping ratio is too large, the open-pit mining cost is high, and the underground mining method should be used instead. An independent production and business unit that mines ores with a certain mining realm in o...

AI Technical Summary

Problems solved by technology

[0003] Open-pit mines will produce a large number of flying rocks during blasting, and the flying rocks flying around will easily cause injury to operators. The existing open-pit mine blasting fly-rock protection devices are inconvenient to move and position and have single functions. At the same time, the existing open-pit mine blasting fly-rock protection devices The overall protection area cannot be adjusted, and it cannot meet the needs of different overall protection areas in different situations, which is inconvenient to use
