摘　　要：煤矿掘进工作面由于受到跨巷上顶存在的原有冒落空洞影响,对掘进安全施工构成很大威胁,如果在施工过程中对冒落空间处理不善,将会带来严重的安全隐患,危险安全生产。针对串草圪旦煤矿,在6100辅运巷(北段)跨中央变电所上顶掘进过程中,新掘巷道与原有变电所硐室存在上下十字交叉关系,两巷层间距较薄且新掘巷道下方原有硐室上顶存在空洞,给安全生产带来隐患。通过分析研究,采取了一系列措施,并取得良好效果。Due to the influence of the original caving cavity on the top of the cross roadway,the driving face of coal mine poses a great threat to the safety construction of the driving.If the caving space is not handled properly in the construction process,it will bring serious potential safety hazard and dangerous safety production.Aiming at Chuancao Gedan Coal Mine,in the process of 6100 auxiliary transportation roadway(North Section)driving across the top of the central substation,there is a cross relationship between the new roadway and the original substation chamber,the distance between the two roadway layers is thin,and there is a hole in the top of the original chamber under the new roadway,which brings hidden danger to safety production.Through analysis and research,a series of measures have been taken and good results have been achieved.
