主　　题：coal pillar subsidence control fuzzy failure analysis 

摘      要：Randomness and fuzziness involved in rock failure analysis are discussed in the present *** stochastic process is introduced to simulate pillar/strata deformation *** shows that the evolution from damage to failure of the rock materials under complex stress environments conforms to diffusion *** pillar strength is analyzed using fuzzy failure analysis in two coal mines.
