摘要
Abstract
Mine fully - mechanized caving mining technology is used to exploit No. 8 coal seam in Guobei coal mine. In order to evalu- ate and classify the top - coal caving and drawing characteristics of No. 8 coal seam, taking 8203 working face as an example, using mining depth, thickness and strength of coal seam, thickness and strength of parting, crack growth degree as evaluation factors, fuzzy math method and function calculation classification method combined with AHP （Analytic Hierarchy Process） are adopted to evaluate top coal caving and drawing characteristics. As a result, analysis and practice show that top - coal caving and drawing characteristics in 8203 working face is extremely good.关键词
