Abstract

The utility model discloses a full-face bolt mesh support of fully-mechanized mining face. The bolt mesh (4) and the anchor rod (5) of the support are arranged on the top and the two sides of a laneway (1). An anchor line (6) and a steel belt (3) are arranged on the top of the laneway (1). The bolt mesh (4) on the top of the laneway (1) is a metal mesh. The bolt mesh (4) is supported by the steel belt (3). The bolt mesh (4) at the two sides of the laneway (1) is a plastic mesh. The utility model can improve the self-bearing force of the surrounding rocks of the laneway, avoid roof separation and accident potential and is favorable to safe production. The utility model provides effective support space for the installation and the debugging of fully-mechanized mining equipment, saves support material and reduces the labor intensity for workers greatly.

Description

Combine to adopt and cut a full section bolting with wire mesh
Technical field:
The utility model relates to the support technology field of mining tunnel, and particularly a kind of comprehensive adopting cut a full section bolting with wire mesh.
Background technology:
Mining tunnel adopt dark big, adopt traditional shed shoring form when pressure is big usually, support does not have setting load to top board, causes the roof delamination inbreak easily, when cutting a secondary brush great achievement lane, roof fall accident easily takes place during changing beam.For strengthening roof timbering, need a large amount of i iron of input to beat tendency and lift the canopy reinforcing, the feasible intraocular effective support space of cutting is few, is unfavorable for the installation of fully-mechanized mining equipment, expanding simultaneously to cut needs between eye and working face equipment installation period to drop into a large amount of mine timber and a dead lift, and labor strength is big.
The utility model content:
The purpose of this utility model provide a kind of combine to adopt cut a full section bolting with wire mesh, can improve roadway surrounding rock from load, avoid roof delamination, for the installation and the debugging of fully-mechanized mining equipment provides effective support space.
The technical solution of the utility model is: described a kind of comprehensive adopting cut a full section bolting with wire mesh, the top that the anchor net of this supporting, anchor pole are installed in the tunnel and the both sides in tunnel, and anchor cable, steel band are installed in the top in tunnel.
The anchor net at top, described tunnel is a wire lath, and off the net of anchor is held up by steel band, and the anchor net of both sides, tunnel is a plastic wire.
Described anchor net adopts iron wire braiding diamond mesh, and steel band adopts the W-shaped steel band.
Described anchor cable adopts the top in steel strand resin anchor cable wedging tunnel, and is " five flowers " eye layout, the top in anchor pole wedging tunnel and the both sides in tunnel, and anchor pole is an array pitch and arranges.
The anchor pole at top, described tunnel adopts the screw-thread steel anchor metal, and the anchor pole of both sides, tunnel adopts the folding wedge wood bolt.
The utility model can improve roadway surrounding rock from load, avoid roof delamination, stop accident potential, help safety in production, for the installation and the debugging of fully-mechanized mining equipment provides effective support space, needn't remove local supporting for fully-mechanized mining equipment is installed again, simplify mounting process, improve installation rate, improve the driving speed and the supporting effect of mining, save a large amount of rigid trestles and mine timber, save support material, significantly reduce labor strength.
