Dynamic action simulation system and preliminary experiments of coal seams and gas
چکیده انگلیسی

In order to study the dynamic action and physical effects of coal seams and gas, a simulation system for this dynamic action was developed and a physical model built in our laboratory. Using this newly built model, the volume of coal outbursts and the temperature during the outburst process were studied. The results show that: 1) for coal seams with similar structure and components, two factors, i.e., gas pressure and ground stress affect the volume of coal outbursts, with gas pressure being the more important of the two and 2) the changes in coal temperature, both its increase and decrease, are affected by ground stress and gas pressure, it is a process of change. Preliminary tests show that the system can simulate the dynamic interaction of coal and gas, which is helpful for studying the dynamic mechanism of solid-gas coupling of gas and coal.
