摘　　要：在分析顶板结构的基础上,建立了组合悬臂梁结构模型,采用理论分析的方法实现了对周期来压步距和来压强度的定量预测,揭示了综放面石炭系C3-5~#层大小周期来压规律的本质。预测方法应用以来,成功预测了周期来压步距和来压,提高了预测预报的精度和可靠性。Based on the analysis of the roof structure,set up a composite cantilever beam structure model,using the theoretical analysis method to realize the quantitative of the periodic weighting step and ground pressure strength prediction,reveals the essence of the larger and small periodic pressure law in the Carboniferous C3-5#layer of fully mechanized caving face.Since the prediction method has been applied,the roof weighting step and the periodic weighting have been successfully predicted,and the accuracy and reliability of the prediction have been improved.
