Abstract: Aiming at the problems of how to improve the accuracy of simulation animation and rendering time efficiency in the production of video animation of coalbed methane mining mode, this paper analyzes and summarizes the production process of 3D animation simulation of coalbed methane exploitation, and expounds three-dimensional simulation technology, IK skeleton animation technology, custom rope editing technology, special effect technology of extraction animation, dynamic deduction technology of split shot and GPU of Vray rendering device rendering technology, these key technologies have been applied in the dynamic simulation deduction of coalbed methane coordinated mining mode in Jincheng Mining Area, and achieved good results. It helps users understand coal and CBM mining technology more intuitively and efficiently.
