摘要
设计了基于煤层倾角变化的相似材料模型试验,以工业近景摄影测量系统为观测手段,对所获得的数据进行处理,得出不同倾角模型地表的下沉曲线。分析了随着煤层倾角的变化地表下沉曲线形态的差异性,并基于概率积分法对预计模型进行修改,通过MATLAB软件进行函数拟合,得出缓倾斜煤层与急倾斜煤层开采地表预计都适合的预计函数数学模型。
The tests of similar material model based on the dip angles variation of coal seam was designed. With the aid of the close range industry photogrammetry system, the collected data are treated to obtain the surface subsidence curve with different coal seam dip angles. The difference of surface subsidence curves with the variation of dip angles of coal seam are analyzed, and the prediction model is modified based on probability integral method. The function fitting is realized by MATLAB software to obtain the new prediction model which all suitable for coal mining of gently inclined seam and steep seam.
