开采引起的山区地表移动与变形预计

Prediction of Surface Movement and Deformation Caused by Extraction in Mountainous Region

为了推动山区“三下”采煤试验,充分合理地开发煤炭资源,必须首先解决开采引起的山区地表移动与变形预计。以下就近水平煤层开采,地面倾角小于30°的山区地表移动与变形预计问题作一些探讨。“开采影响下的山区地表移动”

Further to the paper entitled 'Surface Movement Caused by Extraction in Mountainous Region' , prediction of surface movement and deformation is discussed. The functional formula for surface movement and deformation is derived from their numerical relationship. Method of prediction and its precision are explained with examples. The effect of steep surface on movement and deformation are briefly analyzed. The prediction formula and method are suitable for mining near-flat coal seam with surface inclination less than 30°.
