Abstract

The invention discloses a heat-fluid-solid coupled coal body true-triaxial shearing percolation experimental device for various mediums and an experimental method thereof. Based on the prior art, the experimental device adopts a separate-structured true-triaxial experimental box and a special-structured rubber tray which matches the experimental box. Thus, during the test-piece shear deformation operation, authenticity, accuracy and reliability of simulation will be greatly raised, and it is convenient to monitor. According to the experimental device, a test-piece to be detected exerts a force simultaneously in triaxial directions of a three-dimensional coordinate system. Therefore, the experimental device is truly a true-triaxial shearing percolation experimental device. In addition, the experimental device can be used for a gas heat-fluid-solid coupled coal body true-triaxial shearing percolation experiment and also can be used for a liquid (water) heat-fluid-solid coupled coal body true-triaxial shearing percolation experiment. In comparison with the prior art, the experimental method has characteristics of high simulation degree, real and accurate detection result, good reliability and the like.

Description

technical field [0001] The invention relates to a shear seepage device and an experimental method thereof, in particular to a thermal-fluid-solid coupled coal body true triaxial shear seepage experimental device and an experimental method thereof which are suitable for various media. Background technique [0002] Coal permeability is the basic parameter to study the migration of gas or water in coal, and its simulation experiment research is the most common research method at present. [0003] The simulation experiment devices in the prior art have one thing in common, that is, the test boxes used for the test pieces are all integrated structures, and only a single normal stress is considered. There is a large degree of distortion or misalignment in the shearing effect generated; moreover, only the simulation experiment research of liquid seepage can be carried out, but the gas research cannot be carried out, so there are great limitations in use, and it is impossible to stu...
