为了合理地评价煤矿工作面冲击矿压的危险性。通过采用层次分析法对影响冲击矿压的自然条件因素、地质动力因素、开采及技术因素、组织管理因素等多种因素进行分析研究,从而确定各影响因素权重,建立冲击矿压危险性的多层次模糊综合评价模型,进而对冲击矿压危险性的低危险、中等危险、高危险作出定量评价,提高对冲击矿压危险性评价的准确性和科学性。研究结果表明:采用所建立的模型所得评判结果能较准确地反映工作面的危险程度,精度较高,为煤矿工作面冲击危险性分析评价提供了一种可行的思路和方法。
In order to rationally evaluate the mine pressure bumping dangers of the coal mining face in a coal mine, the hierarchical analysis method was applied to the analysis and study on the natural condition factors, geological dynamic factors, mining and technical factors, organization management factors and other factors affected to the mine pressure bumping. Thus each factor affected to the weight could be set up. The multi hierarchic fuzzy evaluation model of the mine pressure bumping dangers was established. Therefore the quantitative evaluation on the low danger, medium danger and high danger of the mien pressure bumping dangers could be conducted, the accuracy and sciences of the mine pressure bumping danger could be improved. The study results showed that the judgment results from the established model could accurately reflect the danger degree of the coal mining face and the high accuracy. The study results could provide a feasible idea and method to the mine pressure bumping danger analysis and evaluation of the coal mining face.
