摘要
Abstract
Use of numerical simulation with field measurement methods, studies the roadway stress, internal distribution and evolution of rock ifssures. Through the big sides along the roadway, the formation mechanism of small structures, movement pattern and characteristics analysis revealed a large structural principle of the overlying rock and small structural stability and stabilizing inlfuence on the roadway, which is proposed to ensure that coal strong pressure mine roadway stability control mechanism of the column. While using theoretical analysis and numerical calculation method to determine the strong pillar in the thick coal mine roadway reasonable pressure horizons and location for the proposed roadway pressure inside strong pillar mining of high-strength steel mesh and anchor support technology system, and 330 were assisted return airway industrial test.关键词
