Abstract

The invention relates to a material compacting device for a similar material simulation test and a using method. The material compacting device is particularly suitable for a similar material simulation test in the fields of mining engineering and geotechnical engineering. The device consists of a pressurizing plate, a dual-acting hydraulic jack, a dual-acting hydraulic jack base, a hand-operated spiral lift and a hand-operated spiral lift base. The hand-operated spiral lift is controlled to enable the pressurizing plate and the dual-acting hydraulic jack to descend to a suitable position above a testing material, the dual-acting hydraulic jack is controlled to enable a piston of the dual-acting hydraulic jack to vertically move repeatedly, and the pressurizing plate is driven to repeatedly compact the test material. The material compacting device is high in resetting speed and large in pressure, can meet requirements on repeated pressurizing to the test material, and is good in material compacting effect; the compacting range is large, the compacting speed is high, the labor intensity is reduced, and the test efficiency is improved; and the material compacting device is simple in structure, convenient to implement, high in maneuverability, convenient to control and low in manufacturing and repairing cost.

Description

technical field

[0001] The invention relates to a material compacting device and a use method for similar material simulation tests, and is especially suitable for similar material simulation tests in the fields of mining engineering and geotechnical engineering. Background technique

[0002] The similar material simulation test is to use artificial materials with similar physical and mechanical properties to natural rock (soil), according to the actual prototype of geological conditions such as mines, scientifically follow a certain proportion to make a model, and then carry out roadway excavation and coal mining in the model Working face mining, etc. to simulate stope activities, observe the movement, deformation and destruction of rock formations, and speculate on what happened in the on-site prototype. Due to its clear and intuitive effects, similar material simulation tests play an important role in the research of scientific issues in the fields of mining engineering a...
