ATTRIBUTE MEASUREMENT MODEL AND APPLICATION FOR CLASSIFICATION OF ROCK BLASTABILITY

WEN Chang-ping,LI Rong (Urban Construction Departure of Shaoyang University,Shaoyang 422000,Hunan,China)  
Based on the analysis of main causes of rock blastability,the consistent coefficient f,acoustic impedance K,explosive consumption q,and mean fracture distance d of wallrock are chosen as the criterion indices for rock blastability classification.The attribute measurement model based on attribute mathematical theory is proposed to rock blastability classification.The actual example study indicates that the synthetic assessment result agrees well with gray optimization model and fuzzy synthetic evaluation model,which validates that the proposed model is feasible,effective and reliable in rock blastability classification.As attribute recognition theory can successfully resolve certain issues with a number of fuzzy attributes in comprehensive evaluation,and its confidence criterion is established on the basis of the ordered evaluation sets,consequently,it enables the evaluation results be more reliable.The proposed model is forthright in theory,simple and convenient in method,and the evaluation result is reliable,so it is applicable in practice.
