Abstract: The adjustment of underground traverse control network and the prediction of holing-through survey errors are the core knowledge modules of the course Mining Surveying,and the abstraction of their theoretical framework and the complex ity of their technical methods pose dual challenges to both classroom and practical teaching.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 un derground traverse control network and combined with actual measurement data,a simulation of adjustment of underground trav erse 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 sur vey error prediction:simulation of the principle of holing-through survey error prediction,simulation of point-position error dis play,simulation of the optimal position of gyroscopic orientation edges,and simulation of the optimal scheme selection for ho ling-through survey.The system is easy to operate and has a clear structure.By combining actual case data from mining survey ing,students can better understand the principles and methods of data processing in mining surveying,as well as carry out inno vative 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.
