Study on the information granularity and rough set clustering of mine accident energy system

摘要

Aiming at the character of mine accident energy information i.e.messy,skimble-scamble,instantaneous,scrappy etc.and based on energy system,information granularity and Rough set theory,a new model for studying mine accident energy information is established.The information that can reflect the accident energy in workspace is divided into numeral granule and character granule by data predicable and symbol attribute,in order to realize the dispersive energy information data.Consulting the comparability and functionary of energy information data set,numeral granule and character granule are filtrated,adjusted,assembled and managed,a new energy information clustering arithmetic is formed.The research indicates that production energy information is ordered in normal production state while it is out-of-order in production accident state.The data point that the number and character of energy information are ranged orderly and too far or too near away from clustering center,basically forms energy information granules core,which is area with high accident probability.On the contrary,the data point that the number and character of energy information are ranged disorderly and reach average distance,basically forms energy information granules group,which is area with high accident probability.
