Problems solved by technology

[0004] Rock test samples are processed from rock cores, which need to be cut and processed into required shapes such as hexagons and cylinders according to the test requirements, and the rock cores are mined from deep areas, where the environment has high pressure and high pressure. The characteristics of temperature, conventional drilling and processing will cause the release of stress and temperature, which will make the core "distorted". The high cost of collecting deep cores with little availability is a problem that plagues the academic and industrial circles

Abstract

The invention discloses a rock test sample cutting device and a cutting method in a fidelity environment, and belongs to the technical field of rock sample preparation. The device includes a fidelity cabin; a displacement unit, which transports the rock core in the fidelity cabin; a cutting unit, which cuts the rock core; a temperature control unit, which controls the temperature in the fidelity cabin; The pressure in the real cabin. The rock test sample cutting device in a fidelity environment of the present invention does not need to manually adjust the position of the rock core, avoids the rock core from being polluted and damaged, and ensures that the rock core is always in the original position under the stress of buried depth and ground temperature. The sample positioning is completed by the external control system of the fidelity cabin, which cooperates with the temperature control unit and the pressurization unit, so that the core to be cut is always kept in the deep in-situ high-temperature and high-pressure environment for cutting and preparation, and the original position of the deep rock is kept to the greatest extent. Features, improve sample preparation efficiency and sample quality, and provide necessary in-situ cores for obtaining in-situ rock mechanical parameters.

Description

technical field [0001] The invention belongs to the technical field of rock sample preparation, and more particularly relates to a cutting device and a cutting method for rock test samples in a fidelity environment. Background technique [0002] With the decrease of shallow resources, deep mining has become an inevitable trend of mineral resources mining at home and abroad. The rock mechanics problems generated in deep mining engineering are the focus of research in mining and rock mechanics at home and abroad. Existing rock mechanics The rock samples for the mechanical test are all obtained by deep drilling, releasing the in-situ stress and in-situ temperature, and then processing them. Therefore, the rock samples no longer have the characteristics of in-situ rock mechanics, and the test results cannot reflect the original mechanical properties of rock. [0003] Therefore, the preparation of rock test samples in a fidelity environment is the primary key issue in the study ...
