煤与瓦斯突出危险程度指标层次分析模型的建立及应用

Establishment and application of hierarchy analysis model to coal and gas outburst dangerous degree index

为了能够选用最能反映煤与瓦斯突出危险程度的指标并以此指标来指导矿井的安全生产,文章基于影响煤与瓦斯突出的影响因素,分析了反映煤与瓦斯突出危险程度的指标,应用层次分析法的基本原理建立了煤与瓦斯突出危险程度指标的评价模型,并进行了实际应用。应用结果表明:采用该评价模型优选的指标较好的反映了煤层的突出危险性,与煤层的实际情况较符合。

In order to select a index which could best reflect the coal and gas outburst and could guide the mine safety production, base on the influence factors of the coal and gas outburst, the paper had an analysis on the index to reflect the coal and gas outburst dangerous degree. With the basic principle of the analytic hierarchy process, an evaluation model of the coal and gas outburst dangerous degree index was established, the actual application of the model was conducted. The application results showed that the index optimized with the evaluation model could be well to reflect the outburst danger of the seam and could be fitted with the actual condition of the seam. The establishment of the model could provide the scientific theoretical basis and the suitable actual evaluation method for the coal and gas outburst prediction.
