Abstract: | Analyzed the factors which affected the coal and gas outburst, then established the corresponding indicator system. Built
a dynamic set-pair analysis prediction model which combined of Markov model and set-pair analysis model, and then it applied
to coal and gas outburst prediction. Finally, compared the prediction results with the actual results. As provided a reference
to the coalmine in safety decision-making. The research results indicate that there are four districts in high dangerous level,
two districts in middle level and one district in low level, which consistent with the actual situation; the dynamic set-pair
analysis model has a good effect in predicting coal and gas outburst. Especially in the continuous time intervals, according
to the data of mined exploration and the connection degree analysis, we can deduce the dangerous levels of unexplored districts
from the historical data. In different districts, the relevant indicators can be adjusted accordingly, so as to enhance the
accuracy of the prediction. |
