为研究不同采高近浅埋煤层采场应力演化规律及支架载荷,采用UDEC离散元数值模拟软件建立近浅埋煤层采场模型,并在不同采高条件下进行开挖实验。模拟结果与现场矿压观测统计结果相似,模拟结果比较可靠。
In order to study the stress evolution law and the support load of stope in different mining near shallow shallow seam, UDEC discrete element numerical simulation software is used to establish the stope near shallow seam. The excavation experiment is carried out under different mining heights. The simulation results are similar to the observation results of on-site rock pressure, and the simulation results are more reliable.
