摘要
涡北矿8#煤层采用综采放顶煤开采工艺,为对其冒放性进行评价和分类,以8203工作面为例,采用开采深度、煤层厚度和强度、夹矸厚度和强度、裂隙发育程度作为评价因素,综合运用模糊数学分类法、函数计算分类法和层次分析等数学方法对顶煤的冒放性进行评价。经过分析评判及现场观测,得出该矿8#煤层的冒放性极好。
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.
