Principles of modelling associated hazards

Author: J. Kabiesz

Natural hazards occurring in mines that can interact by altering their states and forms are called "associated" hazards.

Thus, traditional methods for assessing and predicting their states may appear unreliable.

Therefore, a need arises to find certain of their definitions so that the above-mentioned shortcomings can be eliminated.

This aim can be achieved using the conventional and normalised measures of hazard state assessment, by comparing or summing these hazards in an n-dimcnsional space and by creating linguistic characteristics of the interrelated coincidences.

A suitable tool to accomplish this task is the "fuzzy sets" theory.

This theory may additionally optimise the choice of sets of preventive measures, take into account their conflicts with the coexisting hazards and indicated a preference for the reduction of the dominant hazard.
