Abstract: Simulation teaching is the advanced stage of Computer Assisted Instruction.In order to improve teaching effectiveness，and from views of the deficiencies of the traditional teaching and the advantages of simulation teaching，a simulation teaching system based on VB was developed to predict and control mining subsidence，and then was introduced into the teaching program of mining subsidence.Through discussing the development principle and the function of the system，the functions and characteristics of the three modules were introduced in detail，which include the ground movement and deformation analysis module，the dynamic demonstration module and the mining subsidence control module.According to this system，the human-computer interface was adopted to communicate with the system and to enable students to fully understand and grasp the mechanism of surface and rock failure，and the prediction and control of mining subsidence，thus effectively improving the teaching quality and effectiveness.The practice showed that the introduction of computer simulation into the teaching of mining subsidence can greatly improve the students' comprehension ability and cultivate students' interest in learning.
