Description
technical field
[0001] The invention relates to the research field of stope mine pressure, in particular to a coal mine stope similarity model test system and method with adjustable size and inclination angle. Background technique
[0002] Coal is China's main energy source and plays an important strategic role in the development of the national economy. At present, the mining depth of China's coal mines is increasing at a rate of 8m-12m per year, and the eastern mines are developing at a rate of 100m-250m every 10 years. With the gradual depletion of shallow coal resources, the mining depth of coal mines has gradually developed from the initial shallow part of 200m-300m to the deep part of 700m-800m, and the mining depth of some coal mines has reached more than 1000m. Depth, the problems faced by deep mining are becoming more and more prominent. Compared with shallow and middle-deep mining, the biggest difficulty in deep coal mine mining is the complex mechanical environm...
