Abstract

The utility model relates to a mining device, in particular to a component for shoring the tunnelling under a mine well. The utility model solves the problems that the prior coal-mine tunnel shoring which adopts pure anchor bolts for shoring has poor canopy-guard effect, and the two sides can easily shift so that the canopy-guard effect and the security of the tunnel are influenced. The component comprises a reinforcing mesh which is laid on the roof of the tunnel, top steel bands and top anchor bolts, and side anchor bolts arranged on the two sides of the tunnel. The utility model is characterized in that a top anchor cable is additionally arranged on each top steel band, the top anchor bolts are arranged on the two midmost rows of the top steel bands, top anchor bolts on adjacent top steel bands are staggered and are basically arranged in a Z-shaped array, and the top steel bands are made of channel steel; the component also comprises a reinforcing mesh and side steel bands, which are additionally arranged at two sides of the working face of the tunnel, and at least one side anchor cable is additionally arranged on a side steel band which is spaced at a certain distance. The utility model has simple structure, convenient production, and wide application range, more importantly can enhance the shoring effect and the security degree of the tunnel, can ensure the tunneling speed, and has a certain popularization value.

Description

Mine laneway driving support unit
Technical field
The utility model relates to mining device, is specially a kind of mine laneway driving support unit.
Background technology
The colliery tunnel support technology is the key technology in the coal mining, keep adjoining rock stability, control roadway deformation and destruction are the necessary conditions that realizes mine safety, High-efficient Production, and along with mine develops both in depth and in breadth, the roadway support problem shows more and more outstandingly.Roof timbering for roadway workface mainly adopts full bolt support at present, and the defective of existence is that anchor rod anchored length is less, and body of rod Fracture Force is less, shock resistance is poor, and supporting is not good, in addition, employed steel band strength and stiffness are little, tear easily and break, and protect the top weak effect; And, also adopt full bolt support for helping supporting in two of tunnel, and and lack wire lath and steel band, be easy to cause two to help displacement, cause roof timbering to lose efficacy or weaken.In a word, above-mentioned phenomenon has had a strong impact on roadway support effect and safe coefficient.
Summary of the invention
The problem that the utility model influences roadway support effect and safe coefficient in order to solve existing colliery tunnel support and to adopt full bolt support to exist to protect top weak effect, two to help to be easy to be subjected to displacement provides a kind of mine laneway driving support unit.
The utility model is to adopt following technical scheme to realize: mine laneway driving support unit, comprise spaced apart top anchor pole on the steel mesh reinforcement that is laid on the back, top steel band and the every steel band, also comprise the group's anchor pole that is arranged on the both sides, tunnel, innovative point of the present utility model is to set up the top anchor cable on the every top steel band, the top anchor pole is positioned at middle two rows of top steel band, top anchor pole on the steel band of adjacent top is staggered to be arranged, and is " Z " font generally and arranges, and described top steel band is a channel-section steel.In the prerequisite that guarantees supporting effect, in order further to reduce cost, the quantity of top anchor pole is one on the every steel band described in the utility model.
In order further to strengthen the supporting that tunnel two is helped, prevent that two help displacement to cause roof timbering to lose efficacy, the utility model also comprises steel mesh reinforcement and the group's steel band of setting up in work plane both sides, tunnel, on group's steel band of certain distance, set up at least one group's anchor cable, the quantity of the group's anchor cable on every group's steel band described in the utility model is one, described group steel band can be channel-section steel, also can be the steel band of original structure.
Compared with prior art, adopt structure design of the present utility model to have the following advantages:
1, on the structure of existing bolt support, increases the quantity of anchor cable, can increase anchorage depth greatly, guarantee that anchored end enters stable rock stratum;
2, increase steel mesh reinforcement, anchor cable member, strengthen two and help supporting, the principle of reinforcing when adopting back and two to help strengthens supporting effect greatly;
3, utilize channel-section steel as the top steel band, not only recyclable recycling, and changed the present situation of original steel band strength deficiency;
In a word, support unit described in the utility model, simple in structure, easy to make, applied widely, the more important thing is and can strengthen roadway support effect and safe coefficient, guarantee tunnelling speed, have certain popularization value,
