Description

The utility model relates to mining and can be used in the construction of lining in underground mines.
Known trellised tightening shtrekovye lining [1], including interconnected transverse rods and longitudinal rods with curved ends on one side for engagement with the transverse extreme rod of the previous tightening.
The disadvantage of this puff is that due to the high degree of freedom in the joints of adjacent puffs, the performance of the lining is reduced.
In addition, the connection nodes of adjacent puffs are located inside the gutters of the special profiles of the support frames, which eliminates the possibility of using the gutters as additional containers for filling with backing material, the adhesion of the frame support to the sides of the workings and the longitudinal stability of the frames are reduced.
These shortcomings reduce the reliability of the lining and the effectiveness of maintaining production.
Also known is the tightening of the lining of the mine workings, including longitudinal and transverse rods interconnected to form a metal grate, the longitudinal rods being made with protruding curved ends located inside the special profiles of adjacent frames, and the transverse rods are curved along the outer frames of the lining, while the ends of the longitudinal tightening rods bent with the possibility of interaction with the inner surface of one of the walls and the bottom of the special profiles of the frames, and one of the longitudinal rods of the tightening has a bar clamp, about yn end of which is rigidly secured to it, and the other curved, with coverage special profile flange frames one of [2].
The disadvantage of this lining is the limited drag resistance to the loads from the side of the filling material with lateral rock displacements due to insufficient curvature of the tightening structure, which, when the loads develop, leads to tightening deformations.
The technical result of the proposed utility model is to increase the operational reliability of the SZA grid by increasing the resistance of the metal grating.
The technical result is achieved by the fact that at the intersection four longitudinal and four transverse rods with a diameter of 10-14 mm are intertwined and connected by welding.
The utility model is illustrated by drawings.
In FIG. 1 shows a mesh for self-supporting anchor support (SZA).
The SZA grid consists of transverse 1, 2, 3, 4 and longitudinal 5, 6, 7, 8 rods, forming a metal grid 9. The rods have a diameter of 12 mm, but it can be reduced or increased by 2 mm depending on mining conditions developed by the underground mining method. The diameter of the rods varies in the range from 10 to 14 mm.
The rods are located in two mutually perpendicular directions.
The SZA grid has a square shape. The length of one side is 920 mm.
The protruding ends 10 of the transverse rods 1, 2, 3, 4 extend beyond the dimensions of the metal grill 9 and are directed towards the fastening workings.
The SZA grid is divided into five horizontal divisions and five vertical divisions, each of which has a length of 180, 220, 120, 220, and 180 mm, respectively.
The central cell 11 of the metal grill 9 has a square shape with a side length of 120 mm, and serves to drill a hole and install a self-fixing anchor support.
Four longitudinal and four transverse rods of the SZA grid at their intersections are intertwined and connected by welding, and the interweaving of the longitudinal and transverse rods is as follows:
- the protruding end 10 of the transverse rod 1 is raised to a height of 46-54 mm, but preferably 50 mm relative to the longitudinal rod 8 from the lower side, and the other protruding end 10 of the transverse rod 1 is raised relative to the longitudinal rod 5 from the upper side, while at the intersection with longitudinal rods 7 and 6, the transverse rod 1 is fixed by alternating from the upper and lower sides, respectively;
- the protruding end 10 of the transverse rod 2 is raised to a height of 46-54 mm, but preferably 50 mm relative to the longitudinal rod 7 from the bottom, and relative to the longitudinal rod 8 from above with a lower height, in addition, the transverse rod 2 is raised by 26-34 mm, but preferably 30 mm above the longitudinal rod 6 and lowered under the longitudinal rod 5, and then the protruding end 10 of the transverse rod 2 is raised to a height of 46-54 mm, but preferably 50 mm;
- the protruding end 10 of the transverse rod 3 is raised to a height of 46-54 mm, but preferably 50 mm relative to the longitudinal rod 8 from the bottom, and then the transverse rod 3 is raised to a height of 26-34 mm, but preferably 30 mm above the longitudinal rod 7 and lowered under the longitudinal rod 6, then the transverse rod 3 relative to the longitudinal rod 6 is raised to a height of 46-54 mm, but preferably 50 mm, having been fixed above the longitudinal rod 5;
- the protruding end 10 of the transverse rod 4 is raised to a height of 46-54 mm, but preferably 50 mm relative to the longitudinal rod 8 from the top, and the other protruding end 10 of the transverse rod 1 is raised relative to the longitudinal rod 5 from the bottom, while at the intersection with the longitudinal rods 7 and 6, the transverse rod 1 is fixed by alternating from the lower and upper sides, respectively.
The construction of the proposed utility model is as follows.
The SZA grid is strung on the anchor rod and is installed simultaneously with the introduction of the anchor into the hole, pressing against the output contour of the base plate. In this case, the anchor is introduced into the central cell 11. The protruding ends 10 of the transverse rods 1, 2, 3 and 4 are tightly pressed against the enclosing rocks.
By increasing the resistance of the metal lattice by strengthening the contacts at the junction of the longitudinal and transverse rods, as well as the direction of the protruding ends of the rods towards the fastening workings, the operational reliability of the SZA network is increased.
