摘要(Abstract)：
选择坚固性系数、声阻抗、炸药消耗量,以及平均裂隙距作为岩体可爆性分级评判指标,应用属性测度理论建立岩体可爆性分级综合评价属性测度模型。针对岩体可爆性评价实例进行分析评价,评价结果与灰色优化模型和模糊综合评判法的评判结果一致,从而验证了属性测度模型应用于岩体可爆性分级评价的可行性和有效性。由于属性识别理论能很好地解决某类问题具有多个模糊属性的综合评价,且置信度准则是根据评价集具有有序性这一特点而提出的,因而可使评价结果更为可靠。
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.
