Problems solved by technology

At present, there is still a lack of a monitoring device that can simulate the interaction between the surrounding rock and the anchor cable and monitor the working performance of the anchor cable in engineering practice. The existing monitoring device can only simply test the performance of the anchor cable in the non-working state. Basic performance does not have real practical significance for guiding engineering practice on site

Abstract

The invention provides a device and a method for testing work performance of an anchor rod cable capable of simulating rock layer fracture and separation on basis of electromagnetic effects. The device and the method are applicable to the technical field of roadway simulation for field test of anchor rod cable work performance. The device comprises a top seat and a base, wherein a plurality of hydraulic upright posts are arranged between the top seat and the base; clamping devices are arranged on the plurality of hydraulic upright posts; an electromagnet block is arranged between two groups ofpulling block-shaped clamping bodies. By using the attraction force and the repulsion force of the electromagnet block bodies, the layered electromagnet block bodies generate layer separation or fracture effects in the loading process; the mutual effect of the field surrounding rock and anchor rod cable test pieces is simulated; each performance parameter of the work state of the anchor rod cabletest piece is accurately recorded; positive guidance significance on the field work guidance is realized.

Description

technical field [0001] The invention relates to a device and a method for testing the working performance of a rock bolt based on electromagnetic action for simulating rock formation fracture and layer separation, and is especially suitable for the technical field of simulating roadway on-site testing of the working performance of a bolt. technical background [0002] In the deep mining of coal mines, due to the increase of ground stress, the surrounding rock of the roadway is more likely to deform, and when the deformation of the surrounding rock exceeds the ultimate deformation capacity of the anchor cable, the anchor cable will break. At the same time, in the mining face, due to the impact of strong mining on the coal and rock mass, large deformation will occur, which will cause large deformation of the anchor cable. When the deformation exceeds the ultimate deformation capacity of the anchor cable, The anchor cable will break. The breakage of the anchor cable will cause...
