煤层群分组上行开采相似材料模拟覆岩破坏规律研究
Rule Research on Simulation of Damage to Strata with Similar Materials in Grouping Upward Exploitation of Coal Seam Groups
摘要
Abstract
Through the theoretical analysis and calculation, the paper finds out the height of water fractured zone and figures out the theoretical failure pattern for two coal seam groups after mining. Through simulation with similar materials in the laboratory, the paper studies and analyzes the destruction rule of two groups upward and downward after coal mining, the roof and floor stress distribution law, and the law of strata subsidence. On this ba-sis, the paper obtains maximum water transmitting fissure zone. In simulation experiments with similar materials, we observe the 1st and the 3rd layer after coal mining, and obtain the damage height of overburden rock and the water flowing fractured zone height. The paper compares the data with theoretical analysis, comprehensively ana-lyzes the rules of overlying rock destruction and movement in grouping upward mining and determines the feasibil-ity of ascending mining in the 1st and the 2nd groups.关键词
