AI Technical Summary
Existing technologies cannot scan changes in the structure of coal and rock mass in real time under high-temperature conditions, making it difficult to analyze the multi-physics coupling effects of coal spontaneous combustion fire accidents.
A multi-field coupled testing system for loose coal and rock masses based on in-situ CT was adopted, including an in-situ reaction device, a CT device, a gas supply device, and a gas analysis device. The system gradually increases the temperature through the in-situ reaction device and uses the CT device for tomographic scanning. Combined with the gas analysis device to detect the concentration of gas products, a multi-field coupled evolution model was constructed.
Dynamic scanning of coal and rock mass structure changes was achieved under high temperature conditions. A multi-field coupled evolution model was constructed, which facilitates the analysis of multi-field coupled disaster-causing mechanisms and ensures the stable operation of the CT device and X-ray penetration.
