摘要
本文利用碎块体力学模型对开采沉陷中走向水平移动预计误差大的原因进行了探讨。通过对传统理论模型的修正，获得了新的走向水平移动规律和走向方向开采影响传播角一般不是９０°的结论。经与实测资料对比表明，新的水平移动计算方法具有计算精度高、运用方便等优点。
In this paper,the clastic model is used to study the reason of the large determinate error of the horizontal displacement on strike section in mining subsidence By correcting the traditional theoretical model,the new horizontal displacement law on strike section and the conclusion that the influence propagationangle on strike direction is unusually 90°are obtained.Compraed with measured data,it is shown thatthe new computing method of horizontal displacement has the advantages of high computational accuracvand convenient for application.
