Researchers from Anhui University of Science and Technology in Huainan, China have conducted a study on stress fractures in oil-bearing coal mining. The study focused on the migration and distribution of oil in oil-bearing coal and its impact on gas drainage and control during mining. The researchers used a triaxial seepage experiment and a low field nuclear magnetic resonance triaxial seepage system to analyze the stress-fracture-seepage field evolution. The study found that the pore-fracture structure in the coal was influenced by vertical stress and confined pressure, and that the conductivity channel for oil/gas migration experienced different stages with corresponding oil recovery percentages. The research provides insight into the co-mining of coal, gas, and oil. [Extracted from the article] |
