Abstract: Based on widely adapted mining subsidence prediction technology, using the " platform + plug-ins " development mode, a wide adaptability of mining subsidence prediction software is designed and implemented based on AutoCAD.The software not only realizes a different seam dip angle and terrain conditions subsidence prediction calculation, but also achieves the expected results of two, three-dimensional visualization. The expected results can meet the needs of production in the prediction and control of surface subsidence "under three" coal mining, and has certain practicality.
