Description

Technical Field

[0001] This utility model belongs to the field of underground mine control and measurement technology, specifically relating to a backsight orientation tool for traverse control and measurement in filling method mining areas. Background Technology

[0002] The purpose of traverse control surveying in filling-type stopes is to import high-level control points from connecting roads into the layered roads of the stope, establish a unified stope coordinate system, and accurately measure the approach and mining design on-site. Accurate and efficient completion of stope traverse control surveying provides precise basic data for mining design. Furthermore, traverse points can be used to determine the center and direction of the approach and mining, which is crucial for ensuring safe production in underground filling-type stopes. The placement of traverse control points primarily considers point stability and resistance to collisions with mine loaders and drilling rigs. They are generally placed on the roof of the roadway. When conducting backsight orientation work for traverse control surveying, the erection of backsight control point targets requires the use of tripods and prisms for centering. This method requires leveling and centering, is cumbersome, and results in high workload and low efficiency for surveyors. Therefore, it is necessary to develop a simple backsight orientation tool for traverse control surveying in filling-type stopes to solve this problem. Utility Model Content

[0003] This utility model provides a backsight orientation tool for traverse control surveying in filling mining areas. The purpose is to solve the problem that when carrying out traverse control surveying backsight orientation work, the setting up of the backsight control point target requires the use of tripods and prisms for centering.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] A backsight orientation tool for traverse control surveying in a filling method mining area, wherein a traverse control point is provided at the location of the roadway roof, and the backsight orientation tool is connected below the traverse control point. The backsight orientation tool includes, from top to bottom, a control point reserved line rope, a first vertical line rope, a multi-functional reflector, a second vertical line rope, and a hammer ball connected in sequence.

[0006] The multifunctional reflector includes a rhombus-shaped acrylic plate with crosshairs. When in use, the total station is aimed at the crosshairs to achieve backsight coordinate orientation. The top of the multifunctional reflector is connected to the traverse control point via a plumb line, and the bottom of the multifunctional reflector is connected to the hammer ball via a plumb line.

[0007] Furthermore, the multifunctional reflector is provided with connecting buckles at the top and bottom, through which a vertical line rope is connected.

[0008] Furthermore, the connecting buckle is a 6mm seamless solid ring made of 304 stainless steel.

[0009] Furthermore, the reserved cord, the first vertical cord, and the second vertical cord are all nylon cords.

[0010] Furthermore, the hammer balls are available in two specifications: 500g and 1000g. The appropriate specification of hammer ball is selected according to the air volume in the mining area.

[0011] The beneficial effects of this invention are as follows: Using this device for backsight orientation operations in traverse control surveying in filling-method mines eliminates the need for prism leveling and centering, simplifies the measurement process, reduces the workload of surveyors, and improves work efficiency. This invention has a compact structure, simple principle, is easy to manufacture, low cost, and good performance, making it convenient for conducting downhole traverse control surveying work and highly practical.
