At the same time, it is also necessary for us to test test blocks with average strength. Using a large test machine will consume a lot of resources and the test cost is too high
[0004] In addition, when the existing uniaxial or multi-axial testing machine compresses the test block, it is relatively oppressive, and the compressive force is on the positive, upward, downward or horizontal sides. hard to fix and impossible to achieve

Embodiment

[0022] Example: A simple test device for simulating roadway rockburst

[0023] As a simple test device, this example is used to compress and test test blocks with low hardness, and can achieve multi-inclination compression, enriching and perfecting the simulated rockburst test data.

[0024] The specific structure includes a base 1, the base 1 includes a strip-shaped bottom plate, the two sides of the long side of the bottom plate are provided with a baffle plate 2 fixedly welded to it, and the baffle plate 2 and the bottom plate form a U-shaped test tank , to provide space and a certain shelter for the compression and fragmentation of the test block.

[0025] The position where the test block is compressed is the middle part of the test tank, so a reinforcing lug 3 is set in the middle of the base 1, and the reinforcing lug 3 is a triangular plate extending horizontally outwards, and the middle part of the reinforcing lug 3 is provided with Rib 4.

[0026] The bottoms of bo...

Abstract

The invention discloses a simple roadway rockburst simulation test device, and mainly relates to the field of rockburst simulation devices. The device comprises a base, a long-strip-shaped test groove is formed in the base, a first pressing plate and a second pressing plate are hinged to the two ends of the test groove respectively, a plurality of strip-shaped holes corresponding to the length direction of the first pressing plate are formed in the first pressing plate side by side, and the second pressing plate comprises a plurality of pressing rods corresponding to the strip-shaped holes in position and width. The pressing rod penetrates through the strip-shaped hole so that the first pressing plate and the second pressing plate can intersect to form an X shape, and the first pressing plate and the second pressing plate are driven by electric power to press downwards. The multi-dip-angle compression device has the beneficial effects that multi-dip-angle compression can be realized, and rockburst simulation test data can be enriched and perfected.

Description

technical field [0001] The invention relates to the field of rockburst simulation devices, in particular to a simple test device for simulating roadway rockbursts. Background technique [0002] Rockburst is a kind of destabilization phenomenon in the process of concealing the rupture induced by the sudden destruction of the rock mass around the excavation space after the excavation of the roadway, and is accompanied by the sudden release of the strain energy of the compressed rock. When a rockburst occurs, a crisp crackling sound may be heard from the inside of the surrounding rock, and the rock mass undergoes violent brittle instability failure. Slight rockbursts only peel off rock slices and have no ejection phenomenon. Severe ones can be measured to a magnitude of 4.6, with an intensity of 7 to 8 degrees, causing damage to ground buildings and accompanied by loud noises. It is often easy to cause damage to the excavation work, equipment damage and casualties. [0003] S...
