The invention discloses a mine goaf instability risk assessment method and system. Compared with the prior art, the method has the advantages that the goaf stability safety coefficient is quantitatively calculated, the two failure mechanisms of shear failure and tension failure of the surrounding rock of the goaf are considered at the same time, scientific quantitative grading evaluation of the instability risk of the goaf is achieved, the tension failure mechanism of the surrounding rock of the goaf is comprehensively considered, and the evaluation result is accurate. 本发明公开了一种矿山采空区失稳风险评估方法及系统。与现有技术相比，本发明通过定量计算采空区稳定性安全系数，并同时考虑了采空区围岩发生剪切破坏和张拉破坏两种破坏机制，实现了对采空区失稳风险的科学定量分级评价，对采空区围岩的张拉破坏机制考虑全面，评价结果准确。
