通过FLAC3D模拟实验方法分析10煤层在采动效应影响下顶、底板岩体变形破坏和矿压显现分布规律,并且给予了定量评价和预测,底板破坏裂隙发育最大值为22 m,为开采10煤层提供了理论依据。
Through the FLAC3D simulation experiment, the top and bottom rock mass deformation and failure modes and the occurrence and distribution of underground pressure in No 10 coal seam under the influence of mining effect are analyzed, and the quantitative evaluation and prediction are given. The maximum value of bottom fracture plate fracture development is 22 m. Provided a theoretical basis.
