Abstract: This paper introduced the method to program Mining Subsidence Predict and Analysis System based on MATLAB. Mainly in theory of Mining Subsidence, structure and function of the system, how Matlab used, advantage in Mining Subsidence Predict and Analysis. An example was used to validate the program at last, the results of predict tallies the result computed with hand, the result of observation and computed with new parameters were consistent in part of parameters computed. Those test proved the results of the system are credibility. The system realized visualization of Mining Subsidence Predict, have good interface with SUEFER and GIS, convenient for after process and analysis.
