Research and development of coalmine hazard monitor control and early warning system

Based on GIS, Bayesian networks, using object-oriented programming idea, exploratory conduct coalmine hazard monitor control and early warning research, developed visual management system of dynamic digital ventilation network (DDVS). In this paper, coalmine hazard monitor control and early warning study is focused on ventilation, gas control, fire control and dust control. The DDVS system is developed with modern safety management principle and based on the geographic information system. It has important theoretical and practical significance in improving coalmine safety management theory, promote coalmine safety management decision-making level, solve coalmine hazard identification problem, improve coalmine hazard early warning ability, reduce accident rate and then raise the overall safety management standards of coalmine.
