摘　　要：采掘接替关系是衡量煤矿安全生产的基本要素之一。以寺河煤矿二号井为例,采用以“无煤柱自成巷工法”为主要内容的系统思维方法,有效降低矿井全年掘进总量,从而缓解采掘接替紧张状况,保障了矿井科学、有序的安全生产活动。Mining and excavation replacement relationship is one of the basic factors to measure the safety of coal production.Taking the No.2 well of Sihe Colliery as an example,the systematic thinking method with the main content of "self-forming roadway without coal pillar" is adopted to effectively reduce the total amount of driving in the whole year and relieve the emergency of mining and excavation,which guarantees the scientific and orderly safe production activities of the mine.

关 键 词：回采巷道布置 采掘接替 无煤柱自成巷工法 万吨掘进率
