摘　　要：为分析沙沟岔煤矿5201盘区上行开采的可行性,简单介绍了5201盘区上行开采背景,以及国内外对上行开采的研究情况。结合沙沟岔矿井的工程地质情况,对沙沟岔矿井5201盘区上行开采进行了探讨分析。分别运用比值判别法、三带判别法、围岩平衡法、数理统计法对上行开采进行了量化分析,提出了上行开采的安全技术措施。通过分析,得出5-2煤层采用长壁综采技术开采后,上煤层5-1煤层处于冒落带之上和导水裂缝带范围内的上部,5-1煤层会出现整体下沉,但不会发生足以影响5-1煤层正常回采的台阶下沉;采取一定的技术措施后,5-1煤层上行开采在理论上是可行的。In order to analyze the feasibility of upward mining in panel 5201 of Shagoucha coal mine,the background of upward mining in panel 5201 and the research situation of upward mining at home and abroad are briefly introduced.Combined with the engineering geological conditions of Shagoucha coal mine,the feasibility analysis of upward mining in panel 5201 is carried out.The feasibility of upward mining is analyzed by using ratio discrimination method,three zone discrimination method,surrounding rock balance method and mathematical statistics method,and the safety technical measures for upward mining are put forward.The analysis shows that after the No.5-2 coal seam is mined by longwall fully mechanized mining technology,the upper No.5-1 coal seam is located above the caving zone and the water flowing fracture zone;the No.5-1 coal seam will sink as a whole,but it will not affect the normal mining of No.5-1 coal seam;after taking certain technical measures,the upward mining of No.5-1 coal seam is feasible in theory.
