Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Such as figure 1 , figure 2 As shown, the sealing structure 1 of the present invention includes an I-shaped steel frame 9, a steel plate 5, a sleeper 6, broken gangue 7, a spring 12, a masonry sealing wall 8, a pressure sensor 10 and the connector between them: a steel pipe sleeve 11. Bolt I17, Bolt II20. There are 10 caves 16 on the top plate 15, the bottom plate 14 and the two gangs 19 of the chamber 21, among which 3 groups (6) are arranged symmetrically on the two gangs 19, and 2 groups (4) are arranged on the top board 15 and the bottom board 14 correspondingly. ), the depth of the rock pit 16 is greater than 50cm, and the rock pit 16 on the top plate 15 and the bottom plate 14 of the chamber 21 and the rock pits 16 of the two gangs 19 are respectively in the front and rear two vertical planes, and are arranged on the bottom plate 14 top ...

Abstract

The invention discloses an anti-rock impact blocking structure of an under-construction slope sliding system, which comprises an I-shaped steel rack and a steel plate, wherein the I-shaped steel rack is vertically fixed in a chamber; a masonry blocking wall is arranged at one side of the I-shaped steel rack, and a vertical steel plate is arranged at the other side of the I-shaped steel rack; a sleeper is arranged at one side of the steel plate; holes are formed in the sleeper; springs are arranged between the steel plate and the I-shaped steel rack; one end of each spring is fixedly connected on the I-shaped steel rack, and the other end of each spring is fixed on the steel plate; the outside of each spring is sleeved by a steel sleeve; one end of each steel sleeve is fixedly connected on the I-shaped steel rack, and the other end of each steel sleeve penetrates in the holes of the sleeper; a gap is reserved between each steel sleeve and the steel plate; and crushed gangue is filled in the space between the sleeper and the masonry blocking wall so as to form a crushed gangue filling layer. The impact force of rock is consumed by the crushed gangue filling layer and then transferred to the masonry blocking wall, so that the impact force applied to the masonry blocking wall is greatly reduced, and then the reliability of the blocking structure is increased. The invention also provides a construction method of the anti-rock impact blocking structure of the under-construction slope sliding system.

Description

technical field [0001] The invention relates to the field of development of metal mines, in particular to a rock impact-resistant plugging structure and a construction method for a slide breaking system under construction. Background technique [0002] The construction of the slip-breaking system is an important development project for metal mines. The slip-breaking system is an important channel for ore transportation in the production of metal mines, and it is also the throat for storing and transshipping ore. Compared with coal mines, metal mines adopt the ore-breaking system to draw ore, which has the characteristics of saving transfer equipment, no lifting, convenient production management, and large production capacity. In the construction process of the entire metal mine, the construction of the slip-through system takes a long time, is difficult, and implies a large number of risks of construction accidents. In order to speed up the construction progress of the chut...
