摘　　要：近距离煤层群开采中,在下煤层采空条件下,上煤层开采受煤层间距、下煤层采高等诸多因素的影响。通过研究上行开采技术特点及其影响因素的内在关系,基于AHP理论建立上行开采可行性评价模型;并对各级指标权重值计算分析,进行一致性检验。根据上行开采模式特点,对其可行性评价等级进行划分,并以恒源煤矿45采区上行开采为工程实例,分析计算其可行性评价总值,进而判定该条件下上行开采是可行的。In the mining of closed distance seam group, the upper coal seam mining is influenced by coal seam interval, mining height of lower coal seam and other factors under the condition of emptying lower coal seam. Through studying the internal relation between the technical characterstics of ascending mining and its influencing factors, this paper established the feasibility evaluation model of ascend- ing mining based on AHP theory, calculated and analyzed the index weight values of all levels, and consistency check is done. Accord- ing to the characteristics of ascending mining mode, its feasibility assessment levels are divided. Taking the ascending mining in No. 45 mining areas of Hengyuan coal mine as engineering example, this paper analyzed and calculated the feasibility evaluation gross value, and then determined the feasibility of ascending mining under these conditions.
