中文摘要：

针对铀矿井通风系统实际特征，合理确定其评价指标体系，建立了基于灰色关联理论的铀矿井通风系统合理性灰色综合评价模型。该模型利用关联度判断评价数据序列与参考数据序列的接近程度，尽量减少个人主观臆断带来的弊端，其评判结果更符合实际，评价结果更可靠。利用该模型对3个铀矿井的通风系统进行评价，方法简便，易于使用，评价结果与实际相符，为铀矿井通风系统合理性评价提供了一种新的方法和思路。

英文摘要：

Aiming at practical character of ventilation system in uranium mine well, through deciding the evaluation index system, a grey comprehensive evaluation model for rationality of ventilation system in uranium mine well is established based on grey correlation theory. The model judges the proximity of evaluation data and reference data of evaluation indexes by correlation degree, in which the disadvantages of individual subjective judgments are minimized, and the evaluation result is more realistic and more reliable. The model has been applied to ventilation system of three uranium mines proving that the method is simple and easy-to-use. The evaluation result complies with realistic state. It provides a new methodology for rationality evaluation of the ventilation system in uranium mine well.
