摘要
为提高煤与瓦斯突出预测指标选择和评价的准确性,并确保多指标评价体系的系统完整性及预测指标的区间连续性,更准确地指导现场突出预测指标的选定,根据灰色区间数关联决策理论,建立煤与瓦斯突出预测指标评价与决策的加权三指标区间数关联决策模型,将3个评价指标共同引入模型作为煤与瓦斯突出预测指标的评价标准,并充分考虑其属性和权重值,结果规范化处理即区间数关联度的计算,以区间数关联度最大为原则确定张集煤矿7#煤层最优煤与瓦斯突出预测综合指标的区间数为[350,400],经过细化研究和评价得到相对最优加权三指标区间数关联决策区间为[370,380].研究结果表明:经过加权多指标区间数关联决策得到的相对最优煤与瓦斯突出预测指标区间数是合理的.
In order to improve the accuracy of predictive indicator choice and evaluation, ensure integrity of multi index system and interval continuity of indicator indexes, and more accurately choose outburst predictor indexes on site, on the basis of grey theory, incidence decision making model of weight three attribute interval number about the predictive indicator evaluation of coal and gas outburst was built; three evaluation indexes were commonly introduced into model as evaluation standard of predictive indexes; attribute and weight value, results standardized treatment were fully discussed. As a principle of maximum interval correlation degree, the optimal interval number [350,400] of comprehensive predictive index of coal and gas outburst at No. 7 Seam in Zhangji coal mine was determined; through refining research and evaluation, the relatively optimal incidence decision interval [370,380] was obtained. The evaluation results show that relatively optimal interval number of predictive index about coal and gas outburst through incidence decision making of weight multi-attribute interval number is reasonable.
