基于冲击风险熵的冲击地压预警研究

Research on shock ground pressure warning based on impact risk entropy

提出一种冲击风险熵,用于冲击地压的预警应用。首先通过分析矿井工作面中影响冲击地压的因素,构建出合适的冲击风险熵指标,通过结合层次分析模型的专家打分表法确定冲击风险熵指标的权重值,并结合熵增熵减估算模型计算出整个系统的熵增值与熵减值,将熵增熵减值带入突变模型判断冲击地压风险的危险程度,从而达到对冲击地压的预警效果。

This study proposes a shock risk entropy for the early warning application of shock ground pressure.Firstly,by analyzing the factors that affect rockburst in the mining face,a suitable entropy index for rockburst risk is constructed.The weight value of the entropy index for rockburst risk is determined by combining the expert scoring table method of the Analytic Hierarchy Process(AHP)model,and the entropy increase and entropy decrease estimation model are used to calculate the entropy increase and decrease of the entire system.The entropy increase and decrease are then introduced into the mutation model to determine the degree of danger of rockburst risk,so as to achieve the warning effect on rockburst.
