摘要
在东滩矿区煤层含气量影响因素分析基础上,利用灰色关联分析理论,通过各种因素关联度大小进行了各种因素对煤层含气量的影响程度研究,确定了影响煤层含气量的主要及次要因素,并分析了地质因素对煤层含气量的影响程度。实例分析结果表明,采用灰色关联分析的方法可对煤层含气量影响因素进行量化分析;该方法计算简单且对数据量要求不高,能够避免异常现象出现,其结果可信度高,可为煤层含气量的分布特征预测提供参考依据。
This paper analyzes the influencing factors of coal-seam gas content in Dongtan mining field, studies the influence level of various factors on coal-seam gas content through grey association analysis, determines the major and minor factors affecting coal-seam gas content, and analyzes the effect of geological factors on coal-seam gas content. The result shows that grey association analysis can perform quantitative analysis, require small data volume and avoid abnormal phenomenon. The method is simple and reliable in calculation, and is useful for predicting distribution characteristics of coal-seam gas content.
