Abstract EN
Mineral extracting involves lots of uncertain factors which take on the typically nonlinear characteristics.
To find out the accidents caused by main factors and make clear of disaster-causing factors and risk sources, a modified risk evaluation model-associated interaction effect analysis method was constructed from four aspects of man subsystem, machine subsystem, working environment subsystem, and operations management subsystem.
With this model, the theory of brittleness relation was applied to analyze closely the connection between mine safety and various subsystems and their interaction effects on mine safety.
Furthermore, brittleness factors were also proposed according to the characteristics of underground mining.
Finally, based on data from working fields and investigation results, taking a typical mine as an example, the analysis was carried out.
The results show that their entropies of brittle relation were equal to 0.006 ± 0.201 i, −0.012 ± 0.221 i, 0.142 ± 0.237 i, and 0.041 ± 0.202 i, respectively.
More exactly speaking, the main brittleness influenced on its safety is the environment subsystem in the mine.
Therefore, the key to controlling mine accidents is to introduce advanced equipment and improve mechanization level to reach the intrinsic safety of the mining enterprise.
The research proves that the modified risk analysis model based on brittleness relation theory is an effective approach to making clear of the state of mine safety and keeping accidents away in time by taking corresponding measures.
