Design of coal mine safety risk prevention and control and early warning system

Abstract

Aiming at problems of lack of systematization, poor timeliness and passive response in coal mine safety risk prevention and control, a coal mine safety risk prevention and control and early warning system was designed. Based on coal mine safety risk database, the system uses risk map to realize dynamic monitoring of each link of risk state change. According to level of abnormal event, hierarchical message push and on-site abnormal linkage disposal are carried out, which improve response and disposal efficiency of abnormal event. Safety grid is used to refine spatial granularity of risk prevention and control, safety index and safety grade assessment of safety grid, operation area and whole mine are realized, and main responsibility of safety management at all levels is effectively implemented. The system is helpful for coal mine to establish comprehensive and multiple safety risk prevention and control system, and effectively improve coal mine safety production guarantee capacity.
