Abstract

The invention relates to mining equipment and is intended for test benches. The purpose of the invention is to increase the reliability of modeling by bringing the folding conditions to full-scale ones. The device comprises a housing 13, a base 3, a working chamber with side 1 and end 2 walls, a model 4 placed in a chamber, electro-screw drives for transferring pressure to the model. The side walls 1 are mobile and have an elastic bond with the housing 13. Each wall 2 is made in the form of two sliding half pistons. The plastic load 6 is placed on model 4, which is used as lead shot or baryt powder. At the base 3 there is a compensating malleable element 5, made of kaolin. The pressure on the half piston 2 is transmitted. from the rod 9 by means of rods, pivotally connected to it. Model 4 is subjected to pressure from both sides. Testing the pressure from the half piston 2 ,, the model is compressed. During compression, it pushes walls 1, and half-pistons, pushing apart, eliminate the gap between walls 1 and 2, this ensures the integrity of the model. When the model is crushed, the excess pressure is compensated by the load 6, which creates conditions that are close to the tectonic processes in the Earth's crust. 2 hp f-ly, 3 ill. (L

The invention relates to mining engineering, in particular to test benches for simulating the folding of sedimentary rocks under pressure.

The aim of the invention is to increase the reliability of modeling by approximating the folding conditions to natural,

Figure 1 shows the device, a general view; figure 2 is the same, top view; on fig.Z - section aa in figure 1.

The device for modeling the build-up pool contains a rectangular working chamber consisting of sliding-side walls 1, sliding end walls 2 and a base 3 in which model 4 is placed on a compensating pliable element 5 made of kaolin, on top of the model is worn plastic cargo (lead shot) 6.

Sliding. Front walls 2 (or half pistons) are made of plates bent at a right angle. The pressure is transferred to the half pistons 2 by means of an electro-screw drive consisting of a screw 7, fixedly mounted on the shaft of the electric motor 8, and a rod-nut 9, to which the guiding device 10 provides only translational motion. ,

By means of hinges 1I, laminated rods 12 are attached to the stem 9 (Fig. 2), pressing on the half-piston 2 and pushing the latter apart. Between the walls of the housing 13 and the movable side walls 1, springs 14 are mounted, taking over pressure from the model 4 side,

The longitudinal pressure from the Model 4 side and the transverse pressure from the side walls 1 provide only semi-piston translational motion (Fig. 3). For the purpose of visual observation, the side walls 1 are made of transparent material (Plexiglas).

The device works as follows

A compensating compliant element 5 made of kaolin is placed in the working chamber of the device, then model 4 made of a stack of layers of equivalent materials of different thickness, density and viscosity, with layers of colored materials to facilitate visual observation, filming and photographing. The model is overlapped with plastic load (lead shot)

The pressure on the model is carried out from two sides using electric screw drives in a given mode and to a certain size.

Pressure transfer is carried out by means of rods 9, lamellar rods 12 connected by hinges P with rods 9. The rods are pressurized on half-piston 2.

Testing the pressure from the half of the half-closed 2 (sliding end walls), the model under study is compressed. When compressing, the model pushes the moving side walls, and the half pistons 2, under the influence of the rods 12, move apart to close the gap between the end and side walls, thus ensuring the integrity of the model,

Testing the pressure from the top (end walls) 2, model 4 is crushed to form folds. The overpressure is compensated by a compliant element 5 made of kaolin, a load 6 made of lead shot and springs 14 of the side walls 1, which makes it possible to create conditions for conducting experiments that are as close as possible to the conditions in which the tectonic processes occurring in the earth's crust.

After completing the experiment, the model under study is taken out, cuts are made along the required planes and it is studied
