摘　　要：为了保证磁窑沟矿井二水平13号煤层开拓开采的顺利延深,分析了磁窑沟井田的有关地质资料,并结合矿井目前的采区接替情况和现有的生产系统,制定了矿井二水平13号煤层延深方案,经过安全、经济、技术等方面的综合比较后,最终确定13号煤层延深采用副斜井井筒直接延深和暗斜井相结合的方式,即直接延深副斜井、新掘主暗斜井和回风暗斜井的开拓延深方案,该设计方案对类似条件下的矿井水平延深巷道布置有一定的借鉴意义。In order to ensure the smooth extension of No. 13 coal seam development in the second level of Ciyaogou Mine,the relevant geological data of the Ciyaogou Mining Field is analyzed,and combined with the current mining area succession of the mine and the existing production system,the second level extension scheme is formulated. After comprehensive comparison of safety,economy,technology and other aspects the extension scheme,the final scheme is determined combining the direct extension of the auxiliary shaft and subinclined shaft,in which the auxiliary shaft is extended directly,and a main subinclined shaft and an air return subinclined shaft are constructed. The result can offer reference for the roadway layout in level extension for the mine under similar conditions.
