Pre-buried anti-rockfall net body on surface of mine governing mountain

Abstract

The invention discloses a pre-buried anti-rockfall net body on the surface of a mine governing mountain. The pre-buried anti-rockfall net body comprises a mounting base and a fixed column arranged close to the mounting base. The mounting seat is a rectangular seat; a fixed pile structure is fixedly welded to the lower surface of a base body, the number of fixed piles fixedly welded to the lower surface of the base body is not less than two, and a mounting n base is fixedly installed on a slope of a mine through the fixed pile structure; the fixed column is a round rod, the lower end of the rodbody of the fixed column is buried in the mountain of the mine, and the mounting base and the fixed column are arranged in a grouped mode. The mounting base is arranged, a guide rail is mounted on the mounting base, a sliding seat for mounting the lower end of an anti-falling stone net mounting frame is arranged on the guide rail in a sliding manner, and a buffer spring is arranged between a second-stage baffle on the sliding seat and a first-stage baffle on the mounting seat, so that stones impacting the anti-rockfall net are buffered to a certain extent through the buffer effect of the buffer spring, the stress of the anti-rockfall net is reduced, and the purpose of prolonging the service life of the anti-rockfall net is achieved.

Description

Technical field [0001] The invention relates to the related technical field of mine management, and specifically relates to a pre-buried anti-rockfall net body on the surface of a mine management mountain. Background technique [0002] Rockfall prevention refers to the protection projects for dangerous rocks at cliffs, steep slopes or tunnel entrances. Common prevention and control projects include gabion nets, rockfall prevention nets, rockfall prevention sheds, etc., which are widely used in railways, highways, mines, hydropower The engineering slope protection has excellent effects on the protection of rockfalls, debris flows, avalanches and the treatment of shallow continuous slope disasters. [0003] In the mining process of a mine, the volume of rockfall is usually large, and the height of the falling point is generally high. As a result, when the rockfall rolls down along the slope of the mountain slope, the dynamic potential energy generated by it is relatively large. The ...

Problems solved by technology

[0003] However, during the mining process of mines, the volume of falling rocks produced is usually large, and the height of the falling point is generally high, which leads to the large dynamic potential energy generated by the falling rocks when they roll down the slope of the hillside, which leads to The impact force of the anti-rockfall net is also relatively large, and the installation of the mine anti-rockfall net body in the prior art is fixed installation, which causes the net body to directly bear all the dynamic potential energy of the rockfall rolling. , As a result, the service life of the anti-rockfall net is generally short, and the daily maintenance of the anti-rockfall net is not only costly, but also the process of maintenance and replacement is very troublesome, very time-consuming and laborious
