In order to overcome the effect of low-temperature environment on vertical shaft construction,Kyzyl-Tash Turk Pb-Zn Polymetallic Mine carried out study and experiment on warmth keeping of headframe and the concrete construction.With the help of construction facilities and equipment such as Ⅳ drilling steel headframe,single-hook hoist,centre rotary mucker and metal slip form,and the cooperation of manual excavation and mechanized equipment,measures that go with headframe structure and shaft engineering such as closed warmth keeping,coal heat supply,warmth-keeping sand material and concrete convey minimize the threat of cold weathers to shaft security,quality and progress,effectively improve the intactness rate of important equipment and facilities like main hoisting winch,winch and hoisting sheave to over 95 %,and solve the problem that the concrete strength is lower than that required by design due to low temperature operation environment,making the concrete strength of the shaft reach 92 % of the design.The central air shaft with net diameter 5.5 m and 404 m depth is constructed conforming to the schedule and required quality,laying foundations for successful transition of open pit to underground.
