摘　　要：针对永安煤矿3108运输顺槽和3106切眼掘进过程中遇空区、空巷的问题,采用理论与实践相结合的方法,对可能存在老窑空区、空巷等的位置进行探讨。通过现场实际测量空区、空巷间保安煤柱的距离以及空区、空巷的尺寸等数据后,进行了综合研判,预判A-6空区可能是最后一个空区,预测在掘进约117~135 m处有可能遇见A-10空区,经现场验证A-6为最后一个空区。针对掘进过程中可能遇到的空区、空巷位置,提前采取应对措施,以保障安全生产。In view of the problems of goaf and abandoned roadway encountered in the 3108 transportation gateway and 3106 cut tunneling in Yong’an Colliery,the paper discusses the possible locations of goaf and abandoned roadway by combining theory with practice.On the basis of the distance of security pillar between the goaf and the abandoned roadway,as well as the size of the goaf and the abandoned roadway measured on site,the article also predicts that the A-6 goaf may be the last one,and the A-10 goaf may be encountered at about 117~135 m of the excavation,which has been verified on site and provided guarantee for safe production.
