Blocking structure and construction method for anti-rock impact of slip-breaking system under construction

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...
