摘　　要：立井凿井井架是立井井筒施工期间进行提升和悬吊施工设备而设立的特殊钢结构体。近年来,随着我国矿产资源开发建设的不断发展,矿井的开采深度超过2000 m、井筒直径超过10 m时,现有的凿井井架无法满足施工的需要。研究设计了超深凿井井架,能够满足凿井井筒净直径11 m、凿井深度2500 m的施工要求。为进一步完善超大超深井凿井井架的设计理论,提升深井凿井技术装备水平,利用互联网技术对凿井井架工作状态下杆件的应变进行实测,既可以进一步提升立井井筒施工的信息化水平,也确保了超深立井凿井施工的安全。Shaft sinking headframe is a special steel structure set up for lifting and suspending construction equipment during shaft construction.In recent years,with the continuous development of mineral resources development in China,when the mining depth of the mine exceeds 2000 m and the diameter of the shaft exceeds 10 m,the existing sinking headframe can't meet the needs of construction.The ultra-deep sinking headframe was researched and designed,which could meet the construction requirements of 11 m net diameter and 2500 m depth of sinking shaft.In order to further improve the design theory of super-large and ultra-deep shaft sinking headframe,improve the level of deep shaft sinking technology and equipment,the use of Internet technology to measure the strain of the rod under the working state of the shaft sinking headframe could not only further improve the information level of shaft construction,but also ensure the safety of super-large and ultra-deep shaft sinking construction.
