摘　　要：为了根据实测数据反演出可用的开采沉陷概率积分参数,研究概率积分参数的反演,采用VB语言编制了模矢法求参程序,但是在实际应用中求取开采影响传播角不符合其物理意义。针对此问题,提出了6参数法求取开采沉陷预计参数,并有效解决了概率积分参数反演中的开采影响传播角问题,特别是在数据质量不高时,可以用这种改进的方法获得比较合理的沉陷预计参数。In order to inverse the parameters of probability integral method in mining subsidence with the field data, the pattern search method could get the parameters with VB language, but with which the propagation angle of extraction in is not in accordance with practical application. Aiming to solve this question, this paper proposed the 6-parameter method to obtain parameters of mining subsidence prediction, and solved the question about the propagation angle of ex- traction in parameter inversion based on probability integral method. Especially when the data quality is bad, the authors can use this improved method to obtain reasonable parameters of subsidence prediction.
