Problems solved by technology

However, the indoor test is only based on the test standard, and the impact test is directly carried out on the specimen processed by the anchor rod, which cannot simulate the impact load and deformation of the anchor rod in the actual support state when the surrounding rock is instantaneously destroyed and released energy.

Abstract

The invention relates to the technical field of mine support, and concretely relates to a test bench used for testing the impact load of an anchor rod, and a test method thereof. The test bench comprises an anchor rod used for mine support, and also comprises a work test bench, a driving device, an impact device and an angle encoder, the anchor rod is anchored in the boring model of the work test bench, the driving device is used for driving the impact device to make the impact device obtain initial energy, the impact device is used for instantly bumping an impact beam for arranging an anchor rod pallet in order to apply impact load having an axial direction to the anchor rod, and the angle encoder is used for testing the swing angle of the impact device. The test bench and the test method can realize the stimulation of the anchor rod support work state in a laboratory, can accurately and effectively test the impact load of the anchor rod when surrounding rocks are instantaneously destroyed and release energy, and can realize the sectioning observation of the deformation position of the anchor rod.

Description

technical field [0001] The invention relates to the technical field of mine support, in particular to a test bench and a test method for testing the impact load of bolts. Background technique [0002] At present, bolt support has become a safe and efficient main support method for coal mine roadways, and has been widely promoted and applied in coal mine roadways in my country. Bolt support is to anchor the bolt in the coal rock body, tighten the nut at the end of the rod, apply prestress to the surrounding rock, and restrain the deformation, separation, expansion and slippage of the surrounding rock of the roadway. [0003] The surrounding rock structure, rock formation properties and stress conditions of the coal mine roadway are very complex. For a large number of roadways under the influence of mining dynamic pressure and geological structure, the internal stress of the surrounding rock is suddenly released when the internal stress of the surrounding rock accumulates to a...
