河北金牛能源股份有限公司邢台煤矿为解决地表矸石堆积和建筑物下压煤问题，采用综合机械化固体充填采煤技术对7606工作面进行回采。充填综采与传统综采的岩层移动和破坏特征有诸多不同，文章采用FLAC数值模拟的方法，并结合两带高度计算公式和实际巷道地表沉降观测值，对充填综采的岩层移动变形特征和规律进行了分析总结。结果表明，综合机械化固体充填采煤技术有效地控制了上覆岩层的变形量，确保了地表建筑物不受开采的影响，为国内同类矿山提供了借鉴。
河北金牛能源股份有限公司邢檯煤礦為解決地錶矸石堆積和建築物下壓煤問題，採用綜閤機械化固體充填採煤技術對7606工作麵進行迴採。充填綜採與傳統綜採的巖層移動和破壞特徵有諸多不同，文章採用FLAC數值模擬的方法，併結閤兩帶高度計算公式和實際巷道地錶沉降觀測值，對充填綜採的巖層移動變形特徵和規律進行瞭分析總結。結果錶明，綜閤機械化固體充填採煤技術有效地控製瞭上覆巖層的變形量，確保瞭地錶建築物不受開採的影響，為國內同類礦山提供瞭藉鑒。
