The ratio of mine accidents caused by human factors increased recently. There is a group who often encounters accidents. On the other hands, there is another group who seldom encounters accidents. It though to be possible to decreased the accidents if the knowledge concerning to the hazard can be transfer from the safe group experts to unsafe group members.A new computer program is developed to realize the above idea. The functions of the program are ;(1) a picture or image of a working place is displayed on a display of PC,(2) the user is asked to indicate where and what is thought to be danger,(3) the user point out the danger places to answer the question,(4) PC shows the correct answer and record the uses answer,(5) some movie may be used is necessary.The important idea of this research is to show many figures to experts, then get and save the information as data base for later use of inexpert users. The inexpert can understand the difference easily using the PC graphics images and text from the data base.
