Abstract

The invention relates to a deep rock mass creep impact test device capable of simulating impact disturbance. A rack body is fixedly mounted on a base; an upper piston and a lower piston are mounted ina hydraulic oil cylinder; hydraulic oil is filled between the upper piston and the lower piston; a pressurizing plate is fixedly mounted at the lower end of a pressurizing rod; a pressure sensor is mounted in a screw hole; the lower end of a pull rope type displacement sensor is connected to a circular ring on the surface of a test table through a lifting rope along the vertical direction; the upper outlet of an air tank penetrating the test table through an impact slideway is in contact connection to the bottom of a pressure bearing base plate; a display is arranged on a control cabinet; anelectromagnetic valve is mounted on the side face of the lower part of the impact slideway, and an impact rod is arranged in the impact slideway; and the pressure sensor, an air compressor and the electromagnetic valve are connected to the control cabinet through a wire. The invention relates to the deep rock mass creep impact test device capable of simulating impact disturbance reasonable in structure, simple to mount and operate, adjustable in simulating impact strength and short in test period.

Description

technical field [0001] The invention relates to the technical field of test equipment, in particular to a deep rock mass creep impact test device capable of simulating impact disturbance. Background technique [0002] With the depletion of shallow coal resources in my country, the mining of coal resources is gradually shifting to the deep. According to statistics, as of 2017, there are more than 50 mines with a mining depth of 1000m in my country, and the mining of deep coal resources has gradually become normalized. Under the conditions of high ground stress and strong mining disturbance in the deep part, the mechanical properties of the rock mass change greatly compared with the shallow part, showing strong creep characteristics, which makes the surrounding rock of the roadway prone to large rheological deformation and failure. Therefore, it is of great significance to carry out creep impact test research on deep rock mass and explore the creep failure characteristics of d...
