A Novel Application of Variable Fuzzy Set on Alarming of Coalmine Gas

Coalmine gas disaster is one of the severe natural disasters that restrict the safety production of coalmines. Timely monitoring and alarming of coalmine gas is an important part of security management. In this paper, a novel alarming assessment model of coalmine gas is presented. Based on the information fusion technique of multi-sensor, we introduce the thought of variable fuzzy set to assess complicated and risk coalmine gas. Through information fusion we can get more effective and reliable data about coalmine gas. The method for variable fuzzy set theory can reasonable identify the relative membership degree between the sample indexes and standard interval of each level index, and reasonably determine the evaluation of each sample by varying the model and its parameters. The numerical examples show that the proposed method is feasible and effective, and the evaluation results are reasonable.
