建设立井开拓方式的矿井工程时,主副井提升系统的交替施工可采用立体交叉平行作业施工工艺,以缩短交替施工工期,进而达到缩短整个矿井建设工期的目的。主副井提升系统施工工期主要包括井简装备、混凝土井塔施工、绞车安装、井口及井底设备安装所占用的工期。有的主井提升系统工期还包括箕斗装载硐室施工和设备安装所占用的工期。按常规单行作业施工程序,每个井筒工期一般为16～18个月,有时混凝土井塔滑模施工赶在冬季,还要受些影响。我们在滕南和大屯两个矿区建设蒋庄(年产1.5Mt)、田陈
When constructing a mine shaft project, the alternate construction of the main shaft and the auxiliary shaft hoisting system can adopt the construction technology of three-dimensional cross-parallel operation to shorten the construction period of alternating construction and shorten the construction period of the entire mine. Main and auxiliary shaft hoist system construction period includes well equipment, concrete tower construction, winch installation, wellhead and bottom hole equipment installation period occupied. Some main shaft hoist system construction period also includes skip loading chamber construction and equipment installation takes time. According to conventional single-line construction procedures, each wellbore construction period is generally 16 to 18 months, and sometimes the construction of concrete tower sliding mode in winter, but also affected. We build Jiangzhuang (with an annual output of 1.5Mt) in Tianannan and Datun two mining areas, Tian Chen
