Description

TECHNICAL FIELD

[0002] In the coal mining industry, in the practice of monitoring, collecting and analyzing the deformation degree of the surface data of the roadway surrounding rock of the coal mining face, a target is often used to distinguish the structural differences of the roadway at different mileage positions, thereby improving the accuracy of the roadway surrounding rock surface contour mapping.

[0003] In the actual use process of the existing target ball supporting and positioning magnetic plane bracket, the important component, the positioning magnetic ring, often adsorbs magnetic impurities such as mine dust particles in the free space of the roadway, which is difficult to clean completely and can easily affect the accuracy of the collected data. In addition, the magnetic plane bracket needs to be bonded and fixed with the target hole point in the actual application. After the adhesive solidifies, the magnetic plane bracket is not easy to separate from the target hole point, but there is also a problem that the adhesive surface residue of the supporting base is easy to cause the magnetic ring to shift or fall off when cleaning after the magnetic plane bracket is separated and recovered. Furthermore, when the target ball supporting base is fixed in the pre-drilled hole on the surface of the roadway surrounding rock, the hole size is too large, and the supporting base is not firmly fixed after installation, which can easily cause the target ball to shake under the influence of factors such as wind flow and mechanical vibration, thereby causing poor monitoring result accuracy.
