地质构造复杂程度定量化评价——以涡北煤矿为例

Quantitative evaluation of geological structure complexity:with Guobei coal mine as example

针对涡北煤矿地质构造严重影响煤矿生产问题,通过分析矿井断层发育特征和展布规律,综合断层发育特征、沉积介质和经济技术3方面的因素,建立了矿井构造评价指标模型;采用灰色关联分析方法和等性块段综合指数评价方法,对矿井构造复杂程度作出了定量化综合评价和分类。结果表明,所得评价结果可靠,与矿井揭露基本符合,可为矿井生产提供指导性参考依据。

Aiming at the problems of geological structure developed in Guobei coal mine,which seriously impactes coal production,through careful analysis of the fault characteristics and distribution law,three aspects of repre-sentative factors,i.e.fault development characteristics,sedimentary media,economic-technical conditions were taken to establish a structure assessment index model,and to predict the geological structural complexity of the different sections according of same character to the grey correlation analysis method and index evaluation method of blocks.Same character of the results showed that the evaluation results were similar with the results exposed by the coal mine,the reliable results provide references for production of coal mine.
