摘　　要：总结了我国煤矿沉井法凿井的发展历程和经验。结合沉井原理和工艺,对沉井主要技术特点进行了梳理,分析了传统沉井法在掘进、下沉及控制方面存在的问题和煤矿沉井技术逐渐沉寂的原因。未来城市地下空间建设等领域,"竖井"需求多。在沉井法独特的技术工艺优势、新的需求背景和装备水平条件下,提出沉井法应从下沉深度、井筒直径、地层环境适应性3个方面,拓展应用领域;并提出了管片拼装井壁、掘沉一体、井壁悬吊下沉、钻沉法等研究方向或创新思路,对重新审视和发展煤矿沉井技术具有积极意义。The paper summarized the development course and experiences of the caisson sinking in China coal mine.In combination with the caisson principle and technique,a carding was conducted on the main technical features of the caisson.An analysis was conducted on the existing problems in the excavation,settlement and control aspects of the conventional caisson method and on the steady silence causes of the caisson technology in China coal mine.In the future cities,the underground space construction and other areas would require many"shafts".Under the unique technical and technique advantage,new requirement background and equipment level of the caisson method,the caisson method should develop the application areas from the aspects of the sinking depth,shaft diameter and strata environmental adaptability.The paper provided that the segments assembled shaft lining,the excavation and sinking combination,the drilling and caisson method and other study orientation or the innovation idea would have the active significances to the new review and development of the caisson technology in the coal mine.
