The invention discloses an anti-reflection displacement and multiphase seepage flow physical simulation experiment system and experiment method for coal containing methane. The system comprises a model counter-force and sealing system for coal and rock specimen manufacturing and loading experiments, a stress loading system used for exerting axial pressure, a fluid injection system used for performing anti-reflection and displacement treatment on a specimen and a numerical control system used for monitoring physical and mechanics parameters inside the specimen. The anti-reflection measures suchas blasting fracturing and hydraulic fracturing and displacement measures such as injection of CO2, N2 and the like of deep methane adsorbed coal can be simulated; and the physical and mechanics parameters such as the coal stress, the strain, the temperature and the gas pressure can be monitored in real time by sensors arranged inside the specimen, so that the rules and mechanisms of adsorption and desorption, seepage and migration of the methane in the coal and rock under the condition of high crustal stress can be studied.
Description
technical field [0001] The invention belongs to the technical fields of mining engineering and geotechnical engineering scientific research, and in particular relates to a test device system and a test method for studying the coupling effect of gas-adsorbed coal body and gas, steam, liquid and other fluids under the condition of deep high ground stress. Background technique [0002] Coal is the main energy source in China, accounting for more than 70% of the total primary energy consumption. Since the beginning of the 21st century, the basic characteristics of my country's coal resource endowment and the strong demand for energy have promoted the rapid transfer of coal mining to the deep at a rate of 10-25 m per year. However, the mining conditions have also continued to deteriorate, especially in the deep mining conditions The high in-situ stress, high gas pressure and content in coal seams, and complex geological structure conditions all cause coal mine gas disasters to bec...
