摘　　要：为丰富矿区开采沉陷的预计方法,提高预测的精度,在综合大量文献的基础上,提出了典型曲线法。典型曲线法避免了由理论模型的假设和简化而造成预计公式的误差,提高了预计的精度,通过开发预计程序,方便了数据的处理,实现了典型曲线法沉陷预计的电算化。以山东龙口软岩矿区为例,详细介绍了典型曲线的建立和应用方法,预计结果和实测最大下沉值的绝对偏差为9mm,相对误差为1.1%。In order to enrich the mining subsidence prediction methods and improve the precision of prediction,we synthesize a large amount of references and materials and propose the typical curve method. The typical curve method can avoid the errors of the expected formula resulted from the assumptions and simplifications of theoretical model so as to greatly improve the prediction precision.With wide use of computer technology and development of prediction program data processing can be greatly facilitated and computerization of the typical curve method＇s subsidence prediction realized.Taking Longkou soft rock coal mining area as an example this paper introduces the establishment and application of typical curve method in detail.Field check shows that the absolute deviation of the predicted subsidence and the measured subsidence is 9mm and the relative error 1.1%.
