Protective device for large safety of coal mining and use method of protective device

Abstract

The invention discloses a protection device for coal mining large safety and a using method thereof.The protection device comprises a protection cover, tempered glass is fixedly embedded in the top of the protection cover, a supporting plate is fixedly connected to the bottom end of the protection cover, a rotating door is rotationally connected to one side of the protection cover, and a fixing cover is rotationally connected to the top end of the protection cover through a hinge; a sealing mechanism is arranged on one side of the fixing cover and one side of the protective cover, an anti-collision mechanism is arranged on the outer wall of the supporting plate, a moving mechanism is arranged at the bottom of the supporting plate, a fixing mechanism is arranged on one side of the rotating door, and an oxygen bag is fixedly connected to the bottom end of the fixing cover. By means of the arrangement mode that the protective cover and the rotating door are matched, through connection of the fixed cover, a worker can conveniently stand in an inner cavity of the protective cover, the influence of slag on the worker is reduced, through the moving mechanism, the device can stably move in a mine through a mine tunnel, patrol of the mine is facilitated, and through the anti-collision mechanism, the influence on mine equipment is reduced.

Description

technical field [0001] The invention relates to the field of coal mining, in particular to a large safety protection device for coal mining and its application method. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the distance to the surface is very close, it is generally chosen to directly strip the surface soil layer to excavate coal. This is an open-pit coal mine. Most of the coal mines in my country are underground coal mines. The scope of coal mines includes a large area above and below ground and related facilities. Coal mines are excavated by humans The reasonable space excavated when the geological layer is rich in coal usually includes roadways, shafts and mining faces, etc. [0003] In the process of excavating mines and mine shafts, during the rest period of the mine, it is necessary for staff to carry out re...

Problems solved by technology

[0003] In the process of excavating mines and mines, during the rest of the mine, staff are required to carry out regular inspections of the mine through the mine cars on the mine road to prevent the mine from collapsing. Due to the existing mine car structure Simple, the protective function is not strong, especially in the event of danger, it cannot form a safe protection for the body of the staff
