Title:
LARGE-SIZE TRUE TRIAXIAL COAL-ROCK MASS MULTI-FIELD SEEPAGE COUPLING SYSTEM EXPERIMENTAL DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2024/041145
Kind Code:
A1
Abstract:
A large-size true triaxial coal-rock mass multi-field seepage coupling system experimental device and method, which relate to the technical field of mining engineering experimental devices. The device comprises a triaxial loading system, a seepage system, a seepage sealing system, a back pressure system, a data acquisition and analysis system, and a triaxial loading chamber (49), wherein the seepage system comprises a liquid-injection seepage system and a gas-injection permeation system; and the triaxial loading chamber (49) comprises a triaxial loading chamber steel frame (54), and a rubber sleeve (28) mounted on the triaxial loading chamber steel frame (54). By using servo control, the device has the advantages of high precision, high controllability, tiny errors, etc. The soft and elastic rubber sleeve (28) is used for edge sealing, and therefore the device has the advantages of having a good sealing effect, being convenient to operate and easy to control, etc. The device also has the advantages of a high degree of freedom, high operability, etc., in terms of the selection of a seepage direction. In terms of seepage media, a seepage experiment can be conducted on both liquid and gas, and thus the device has the advantages of wide usage, broad coverage, etc.
