基于层次分析法的岩巷钻爆掘进安全评价研究

 为了定量地综合评价煤矿岩巷掘进安全状况，建立了岩巷掘进安全评价指标体系，利用层次分析法，确定指标权重和评价指标的评分等级标准，获得评价样本矩阵，建立了岩巷掘进安全综合评价模型。根据建立的模型，对回坡底煤矿岩巷掘进实例进行了安全评价，结果与实际相符。安全综合评价的结果，可以为煤矿制定岩巷掘进安全措施及预防对策提供科学依据。

Study on Safety Evaluation of Drilling and Blasting in Mine Rock Roadway Based on Analytic Hierarchy Process

In order to quantitatively and comprehensively evaluation on the safety of rock drivage, the index system for rock drivage safety evaluation is set up. Based on Analytic Hierarchy Process, weighting and ranking standard of indexes are determined, sample matrix of evaluation is obtained, a comprehensive safety evaluation model for rock drivage is established. According to the model, the safety of rock drivage in Hui Po Di mine is evaluated. The evaluation results conform with actual conditions. Results of comprehensive safety evaluation can provide scientific basis for mine to draw up safety precautions and prevention measures during rock drivage.
