Abstract: The necessity of building digitalized safety training system for coal mine by using the visualized simulation technique is addressed in this paper,and some specifications for digitalized coal mine and its designing method are also introduced.By adopting images,voices,texts and cartoons,the trainees can have a direct sense of the whole procedure of coal mine production just like traveling in the digitalized coal mine,and learn the knowledge related to the coal mine safety.By the digitalized safety training system,the safety training quality can be improved,the safety training cost decreased,and thereby the coal mine production safety guaranteed.
