摘　　要：为实现地质构造简单的缓倾斜综采工作面液压支架智能化选型,提出了一种基于加权实例推理的液压支架选型方法。首先,建立了液压支架选型实例库;其次,采用粗糙集理论和序关系分析法进行权重构造;另外,将液压支架的条件属性分为3种类型计算相似度;最后通过匹配实例选型。以某煤矿选型方案为例,并以50组液压支架的属性数据进行验证。结果表明,该方法的准确率为88%,能够为液压支架的智能化选型提供较好的参考依据。In order to realize intelligent selection of hydraulic support for gently inclined comprehensive mining working face with simple geological structure,a hydraulic support selection method based on weighted case-based reasoning was proposed.Firstly,a hydraulic support selection instance library was established;secondly,rough set theory and sequential relationship analysis method were used for weight construction;in addition,the conditional attributes of hydraulic supports were divided into three types to calculate the similarity;finally,the selection was made by matching instances.The selection scheme of a coal mine was taken as an example and verified with 50 sets of attribute data of hydraulic support.The results show that the accuracy of the method was 88%,which can provide a better reference basis for the intelligent selection of hydraulic support.
