为合理评价煤巷锚杆支护效果,通过采用层次分析法对影响煤巷锚杆支护效果的地质条件、支护参数、支护工艺、采动影响、掘进速度、经济效益等多种因素进行分析,从而确定各影响因素权重值,建立煤巷锚杆支护效果的多层次模糊综合评价模型,进而对支护效果作出好、较好、一般、差的定量评价,提高对煤巷锚杆支护效果评价的准确性和科学性。利用该评价方法对王家沟煤矿402巷道锚杆支护效果进行评价,分析结果表明其评价结果与实测数据一致。
In order to rationally evaluate the bolt support effect of the seam gateway,the layered analysis method was applied to analyze the geological conditions,support parameters,support technique,mining influences,gateway driving rate,economic benefit and other factors affected to the bolt support effect of the seam gateway.Therefore,each factor affected to the weight value could be determined and the multi level fuzzy comprehensive evaluation model for the bolt support effect of the seam gateway was established.The support effects could be quantitatively evaluated as good,fair good,normal and poor and the accuracy scientificalness of the bolt support effect evaluation for the seam gateway could be improved.Finally,the model was applied to the bolt support effect evaluation of No.402 seam gateway of Wangjiagou Mine and the evaluation results were the same to the site measured data.
