摘　　要：为确定银星一号井18_(上1)煤开采后13煤上行开采的可行性,选取18_(上1)煤11采区1118_(上1)04工作面为测试地点,综合运用比值法、“三带”判别法及围岩平衡法进行对比分析。比值法计算得到采动影响倍数K=27.95;理论计算“两带”最大高度为46.33 m;围岩平衡法分析得出上行开采的最小高度为27.41 m,均小于层间距92.23 m。通过现场打钻探测18_(上1)煤开采后,裂缝带发育高度为51.16 m,探测结果与理论分析相吻合,证明了13煤上行开采可行。In order to determine the feasibility of upward mining of 13 coal seam after 18_(上1)coal seam mining in Yinxing No.1 mine,1118_(上1)04 working face in 11th mining area of 18_(上1)coal seam was selected as the test site,and the comparative analysis is carried out by using ration method,“three zones”discriminant method and surrounding rock balance method.The ratio method obtained the mining influence multiple K=27.95.The maximum height of the“two zones”is 46.33 m.The analysis of surrounding rock balance method shows that the minimum height of upward mining is 27.41 m,which is smaller than the interval of 92.23 m.The fracture zone development height is 51.16 m after coal seam mining in 18_(上1)through field drilling.The detection results are consistent with theoretical analysis,which proves that upward mining of 13 coal seam is feasible.
