Embodiment Construction

[0025] Below in conjunction with accompanying drawing, the present invention will be further described.

[0026] Such as figure 1 Shown is a schematic diagram of the installation of the rock sample testing platform 3. As shown in the figure, the steps of the installation process are as follows: (I) first place a cylindrical special steel tank 31 with a height of 200 mm and a diameter of 85 mm vertically; (II) place a cylindrical test rock in the center of the steel tank 31 sample 32; (Ⅲ) pour non-shrinkage concrete 33 into the gap between test rock sample 32 and steel tank 31, and keep poured non-shrinkage concrete 33 flush with test rock sample 32; (Ⅳ) after non-shrinkage concrete 33 is hardened, A flange 34 is provided at both ends of the steel tank 3, which are the water inlet flange and the water outlet flange respectively. A water inlet is arranged in the middle of the water inlet flange, and a water outlet is arranged in the middle of the water outlet flange. , and the...

Abstract

The invention discloses a rock permeability testing device for simulating the deep underground rock mass environment, which includes a rock sample testing platform, a temperature control system, a seepage water input system and a seepage water volume acquisition system, and the seepage water input system includes an input power device and a pressure regulator Devices and pipelines, the rock sample test platform includes test rock samples and steel tanks, the test rock samples are sealed in the steel tank by non-shrinkage concrete; the water outlet of the seepage water input system is connected with the water inlet of the steel tank, and the water outlet of the steel tank It is connected with the water seepage collection system, and the temperature control system is arranged around the rock sample testing platform. The invention has obvious beneficial effects, convenient and simple operation, can measure the permeability coefficient of rocks at different temperatures, conduct experiments to verify the influence of the temperature field on the seepage field, record the seepage flow in real time, and reduce errors.

Description

technical field [0001] The invention belongs to the field of mine rock soil testing instruments and equipment, and relates to rock permeability testing equipment for simulating the environment of deep underground rock masses. technical background [0002] In the deep mining of minerals, the temperature of the mine 1000m underground can often reach 40-50°C. In such an environment, the seepage movement and thermal movement inside the deep rock mass continue continuously, and the underground temperature field and seepage field exist. Non-linear complex coupling relationship, the change of seepage characteristics of deep rock mass under high temperature environment leads to the change of seepage field distribution and the influence of temperature change on seepage field distribution. [0003] In order to explore the influence of temperature field on seepage field, it is necessary to test the permeability coefficient of rock mass under different temperature conditions. Contents...
