英文摘要：

This paper analyzed the current situation of surface dynamic prediction software and function and features of MATLAB at present, MATLAB was introduced focusing on algorithm application in the dynamic surface critical technology. Theoretically based on probability integral method combined with dynamic time function, surface dynamic prediction system was developed using MAT- LAB. The results showed that the method could reflect the dynamic characteristics of the surface movement, realize the comparatively accurate analysis and calculation for the effects of coal mining on surface dynamic subsidence, draw intuitively and precisely graphics of surface deformation, which had great practical value in guidelines for mining design and choice for surface buildings protection.
