本文用数据处理方法整理和分析了锡矿山锑矿二十年来杆柱房柱法采场顶板下沉观测资料,归纳成两种典型的顶板下沉速度曲线型式,并用曲线拟合方法得出了该矿杆柱法采场顶板下沉速度方程式;用数理统计方法归纳了多年来的地压资料,把预报采场顶板冒落的现场经验上升到理论上,得出锡矿山杆柱法采场条件下予报顶板冒落的方程式,利用这些方程式进行予报,其准确率达65～67％。本文最后阐明了顶板破坏的全过程,给出了顶板岩石破坏过程的模式。
In this paper, data processing methods to collate and analyze the antimony mine in tin mines in the last two decades of the column roof and pillar method of stope roof sinkage observed data summarized in two typical roof sinking velocity curve type, and curve fitting method The method of mathematical statistics to summarize the ground pressure data over the years, and to raise the field experience of forecasting roof caving to theory, the conclusion is drawn that the stope of stope of tin mine Under the conditions to report to the roof caving formula, using these equations to be reported, the accuracy rate of 65 ~ 67%. At the end of this paper, the whole process of roof failure is illustrated, and the mode of roof rock failure process is given.
