Abstract: The mechanism and laws of rock formation movement and surface subsidence in mining operation are the core basic theories of Mining Subsidence Science. The relevant teaching content is complex and abstract， which is the focus and difficulty of course teaching.In view of the poor classroom effect of conventional teaching methods， and many shortcomings of existing computer simulation teaching of mining subsidence，this paper comprehensively integrates the principles and methods of mining subsidence， the current hot issues of mining subsidence studies and the advanced simulation teaching design methods， a simulation teaching experiment system for mining subsidence based on the MATLAB and FLAC3D is construsted.The system mainly includes two modules:① The simulation module of rock formation movement mechanism based on the coupling of MATLAB and FLAC3D. This module aims at the teaching content related to rock formation movement in mining， and realizes the simulation of the rock formation movement mechanism and the law of formation movement through the complementary function coupling of MATLAB numerical calculation and expression and FLAC3D numerical simulation. ② The simulation module of surface subsidence law based on MATLAB GUI. This module is aimed at the related teaching content of surface subsidence in mining， and based on MATLAB GUI，developed three surface subsidence law simulation sub-modules，namely，mining subsidence prediction principle simulation， intelligent parameter inversion principle simulation and mining subsidence law simulation， and realized the temporal and spatial law of surface subsidence simulation. The system developed in this paper has a friendly interface and simple operation， and students can fully understand the mechanism and law of rock movement， the principle of mining subsidence ， and carry out innovative experiments of solving related prediction parameters by using the human-computer interface， so as to effectively improve the quality and effect of teaching. Teaching practice shows that students' comprehension can be greatly improved， and the innovative spirit and learning interest can be cultivated by using the constructed teaching experiment system. The research results of this paper is help for effectively solving the bottleneck problem in the teaching of Mining Subsidence Science.
