The invention relates to the technical field of
industrial data processing, in particular to an intelligent safety accident early warning method and
system based on
risk assessment, and the method comprises the steps: obtaining a mining operation event, extracting response situations before and after the operation event, checking the response situations with a reference response template, and judging a disturbance response according to the deviation degree; a ventilation
network model is constructed, and when it is detected that a monitoring point is abnormal, management
traceability is carried out along a traversal upstream path in combination with an
air volume distribution proportion; predicting the propagation trajectory of the abnormal gas along the
wind flow path and the time of reaching a downstream node based on the ventilation
network model, and obtaining
spatial correlation analysis; analyzing the disturbance response and the
spatial correlation, calculating a
coupling risk increment, and outputting a comprehensive risk value; judging the critical degree grade of the comprehensive risk value
time series data; and determining a scheduling level according to the combination of the comprehensive risk value level and the critical degree level, when the
critical index indicates to evolve to a dangerous state, improving the scheduling level in advance, and generating a differentiated
resource scheduling suggestion in combination with the propagation trajectory.
