为研究缓倾斜矿体崩落法开采地表移动规律,在程潮铁矿西区埋设监测点进行监测,并得到地表移动变形实测数据。本文通过FLAC三维数值模拟计算,对矿区水平开采引起的地表塌陷与错动机理进行系统研究,并对不同开采阶段的岩层移动特征进行分析。通过模拟计算后可得不同开采阶段典型部位岩体的移动角范围,其结果为预测不同开采阶段地表移动规律提供参考。
為研究緩傾斜礦體崩落法開採地錶移動規律,在程潮鐵礦西區埋設鑑測點進行鑑測,併得到地錶移動變形實測數據。本文通過FLAC三維數值模擬計算,對礦區水平開採引起的地錶塌陷與錯動機理進行繫統研究,併對不同開採階段的巖層移動特徵進行分析。通過模擬計算後可得不同開採階段典型部位巖體的移動角範圍,其結果為預測不同開採階段地錶移動規律提供參攷。
