Movable shield support for inclined manganese ore layer mining

Abstract

The invention discloses a movable shield support for inclined manganese ore layer mining, and relates to the technical field of manganese ore mining. The movable shield support comprises a base, hubsare arranged on the two sides of the base correspondingly, a driving mechanism is arranged in the base, and the driving mechanism is used for driving the hubs to rotate; and a lifting base is arrangedabove the base, a lifting mechanism is arranged between the base and the lifting base, a supporting plate is arranged above the lifting base, a first telescopic air cylinder is installed between thelifting base and the supporting plate, and an inclined plate is arranged on one side of the supporting plate. The movable shield support is reasonable in structure and easy to operate, rotation of thehubs can be achieved through the arranged driving mechanism, then automatic movement of the shield support is achieved, convenience is provided for manganese ore layer mining work, the working efficiency is effectively improved, height adjustment of the shield support can be achieved through the design, and thus the movable shield support is suitable for mining work of manganese ore layers with different inclination angles, wide in application range and high in practicability.

Description

technical field [0001] The invention relates to the technical field of manganese ore mining, in particular to a mobile shield support for mining inclined manganese ore layers. Background technique [0002] In the prior art, mining methods such as open-pit mining method, caving mining method, ore-retaining mining method, and filling mining method are generally used for the mining of manganese ore layers. Among them, the open-pit mining method is the most widely used, and it refers to that in the mining process, The mining method mainly relies on the stability of the surrounding rock itself or a small number of ore pillars and artificial pillars to support the goaf. [0003] At present, when the open-pit mining method is used in the market, the stability of the surrounding rock of the ore body is high. However, when the manganese ore layer in the ore body is inclined, the roof collapse accident is prone to occur due to the poor stability of the surrounding rock of the ore body...

AI Technical Summary

Problems solved by technology

[0003] At present, when the open-pit mining method is used in the market, the stability of the surrounding rock of the ore body is high. However, when the manganese ore layer in the ore body is inclined, the roof collapse accident is prone to occur due to the poor stability of the surrounding rock of the ore body. There are certain safety hazards, and the automation of the existing support is low. During the mining process, manual installation, disassembly and movement are required, and the work efficiency is low, which can no longer meet the needs of the existing market.
