Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] Such as figure 1 As shown, the roadway surrounding rock convergence deformation monitoring positioning nut of the present invention is mainly composed of a bolt nut 1 and a metal post ring 2; the bolt nut 1 varies with the diameter of the bolt used for roadway support; the described The metal column ring 2 is welded on the anchor nut 1 .

[0015] Such as figure 2 As shown, when in use, first determine the monitoring section 3 of the roadway surrounding rock convergence deformation monitoring and the precise position of each measuring point, then install the positioning nut 5 on the anchor rod 4 corresponding to the determined position of each measuring point, and tighten it, and finally, Hook the two ends of the extensometer 6 on the metal post rings 2 of the two positioning nuts 5 for actual measurement.

Abstract

The invention relates to an adjusting nut for roadway surrounding rock convergence and deformation monitoring and a using method thereof, and belongs to the technical field of mine ground pressure monitoring devices. The adjusting nut is designed for solving the problem that coal mine roadway convergence and deformation monitoring and adjusting are difficult. The adjusting nut is mainly composed of an anchor rod nut and a metal column ring. The anchor rod nut changes according to different diameters of anchor rods used in roadway supports, and the metal column ring is welded on the anchor rod nut. The adjusting nut is simple in structure, low in cost, convenient to machine, manufacture and install, and strong in project practicability.

Description

technical field [0001] The invention belongs to the technical field of mine pressure monitoring equipment, and in particular relates to a monitoring point positioning device and a use method thereof, in particular to a roadway surrounding rock convergence deformation monitoring positioning nut and a use method thereof. Background technique [0002] The monitoring of roadway surrounding rock convergence deformation is an important content of roadway rock pressure observation. Through the monitoring of roadway surrounding rock convergence deformation, the stability of roadway surrounding rock can be correctly evaluated, and then the optimal time period for secondary support of roadway can be determined, and the deformation and failure of roadway can be determined. Therefore, it is very important to monitor the convergence deformation of the roadway surrounding rock. Through the monitoring of the convergence deformation of the surrounding rock of the roadway, the stability of t...
