In order to improve the teaching quality of mining surveying courses and help students better understand the basic theory of mining surveying data processing,a mining surveying data processing simulation-based teaching system was developed using MATLAB,integrating mining surveying data processing theories and methods with actual mine observation data. The system is mainly divided into two modules:(1) MATLAB-based underground traverse control network adjustment simulation module. According to the characteristics of underground traverse control network and combined with actual measurement data,a simulation of adjustment of underground traverse control network with additional gyroscopic orientation edges was implemented through MATLAB.(2) A simulation module for predicting holing-through survey errors based on MATLAB GUI. It mainly includes four sub-modules for holing-through survey error prediction:simulation of the principle of holing-through survey error prediction,simulation of point-position error display,simulation of the optimal position of gyroscopic orientation edges,and simulation of the optimal scheme selection for holing-through survey. The system is easy to operate and has a clear structure. By combining actual case data from mining surveying,students can better understand the principles and methods of data processing in mining surveying,as well as carry out innovative tests such as solving the optimal scheme for the number and position of gyroscopic orientation edges. This can cultivate students′ learning interest and craftsmanship spirit,thereby effectively improving the teaching effectiveness and quality of the course Mining Surveying.
