浅埋煤层条带开采固体充填地表沉陷定量控制方法

    Surface Subsidence Quantitative Control Method of Shallow Buried Coal Mining with Strip Mining Solid Backfilling

    • 摘要: 基于等价采高模型和概率积分预计原理分析了固体密实充填全采全充模式在建(构)筑物下浅埋煤层开采的不适应性,分析了建(构)筑物下浅埋煤层开展条带开采固体充填的必要性。在此基础上提出了建(构)筑物下浅埋煤层条带开采固体充填设计原则和沉陷定量控制设计方法。最后将条带开采固体充填设计方法用于某浅埋煤层开采取得了良好的效果。

       

      Abstract: The inadaptability that mining under the building (construct) shallow buried coal seam with solid compacted backfilling full mining full filling pattern is analyzed based on the laws of equivalent mining height and probability integral. We analyze the necessity of strip mining solid compacted backfilling when mining shallow buried coal seam is under the building (construct) structures. On the basis of that above, strip mining solid filling design laws and subsidence quantitative control design method are proposed. At last, this method used in shallow buried coal seam mining obtained the good effect.
