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 geological structure of Wubei coal mine seriously affecting the production of coal mines, the mine structural evaluation index model was established by analyzing the characteristics and distribution rules of the fault, comprehensive fault development characteristics, sedimentary media and economic technology. By using gray relational analysis Method and method of evaluating the synthetical index of equal block, the quantitative comprehensive evaluation and classification of mine structure complexity are made. The results show that the obtained evaluation results are reliable and are basically in line with mine revelation, which can provide guidance reference for mine production.
