摘　　要：在石拉乌素煤矿主井箕斗装载硐室施工中,采取了立井井筒冻结段双层井壁中的特大硐室施工方法。采用此方法仅用33 d便完成了箕斗装载硐室的施工,避免了井筒硐室段多次分段套砌内壁的繁琐转换施工工序,减少了井筒内壁接茬缝。既保证了施工质量及施工安全,又缩短了施工工期,效率高,投入成本低。In the construction of main shaft skip loading chambers in Shilawusu Coal Mine, the extra-large chamber construction method was applied in double-layer shaft wall of the vertical shaft freezing section. By adopting this method, it only took 33 days to finish the construction of skip loading chamber. As a result,the tedious conversion of construction sequence in shaft chamber section of muhiple segmental set-assembling inwall was avoided,and the lining linkage in shaft inwall was also reduced. It not only ensures the quality and safety of the construction,but also cuts down the construction period because with high efficiency and low investment cost.
