岩体可崩性分类方法的模糊综合评判

Fuzzy Synthetic Assessment of Classification of Rock Mass Cavability

冶金矿山工程的围岩稳定性和可崩性评价常用的方法有 :RQD分类法、岩体地质力学分类即RMR法、巴顿岩体质量分类即Q值法。针对某铁矿阶段自然崩落法可崩性评价中 ,同时采用上述 3种方法的分级成果 ,应用模糊数学综合评判法对其进行综合评价 ,得出上述 3种方法在该矿可崩性评价时 ,效果相似的结论 ,为矿山在岩体可崩性评价实际应用中的方法选择 。

Conventionally used classification methods for assessment of rock mass stability and cavability in metallurgical mining engineering include RMR, RQD and Q. A certain iron mine applied simultaneously the classification results of the above 3 classification methods in evaluation of the cavability. The classification results are evaluated comprehensively by fuzzy synthetic assessment. It is concluded that the above 3 classification methods have a similiar effect in evaluation of the mine's cavability of rock mass. These results provide theoretical basis for evaluation of the mine's rock mass cavability.
