【摘要】 从岩石破碎机制分析出发,通过建立岩石破碎比功模态,确定破岩机具结构尺寸、岩石力学特性和破岩工艺三类对岩石破碎比功有影响的参数。引入模糊逻辑法,将上述参数作为模糊逻辑分析的输入变量,岩石破碎比功作为模糊逻辑分析的输出变量,建立用于预测岩石破碎比功的预测模型。将该模糊预测模型应用于某工程实例,通过对比模型所得结果与工程实践中的真实岩石破碎比功,该模型所得结果与工程实践中的真实值比较接近,预测模型设计合理,模糊推理规则能够表达工程实践,在给定输入变量的情况下,该模型可有效预测岩石破碎比功这一重要特征参数。更多还原

【Abstract】 Based on theoretic analysis of specific power of broken hard rock,the mode of specific power of broken hard rock has been established.Tools structure dimension and rock mechanic performance and technique three type parameters,which are interrelated with specific power of broken rock,have been determined.Fuzzy logic method(FLM) has been introduced to predict the specific power of broken rock.To take the above three type parameters for input variables of FLM and the specific power of broken rock for output variables of FLM,a fuzzy prediction model of the specific power of broken rock has been established.The model is applied in a project instance.The comparison of the project practice real value and the model value shows that the model values are close to the project practice real values.This indicates that the model is reasonable and fuzzy if-then rules can express the experience of the project practice.Given input variables,the model can predict effectively specific power of broken rock.更多还原
