However, joint experimental studies of PJSC Yuzhcable Works (Kharkiv) and the Institute of Electrodynamics of the National Academy of Sciences of Ukraine (Kiev) using
UPCAST line US20X-10 as an example on the continuous casting of oxygen-free copper wire have showed that the replacement procedure of the inductor significantly reduces the working life of the furnace [8].
7 m diameter
upcast shafts (VS4A1 and VS4A2) will be raisebored from surface to 800 m.
And the last piece of the monumental jigsaw will be to construct a fan house, which drew fresh air into the mine via the
upcast shaft.
The explosion occurred on a hot day, when there would have been little natural convection, and there was some doubt whether the furnace above the
upcast had been lit the previous night.
There will be a total of six downcast and six
upcast shafts, including two pipe shafts for pumping water.
Once holing has been made with the service shaft and
upcast ventilation is commissioned, the development rate from the exploration shaft can be raised to more than 50 m/d.
However, compared to the present system which has two distribution levels and about 50,
upcast and downcast air-shafts, it is a simple system.
This plant was supplied by Outokumpu Castforrm OY, Finland and uses the
upcast system of manufacturing rod.
Lota is served by four shafts, the
upcast Grande and Alberto and the downcast Carlos 1 and 2 shafts.
Once the Climbers were in place, the evacuation rate greatly improved An additional escape route was established in an
upcast ventilation raise between levels 39 and 41, and another Sky Climber replaced the laborious Rollgliss hoisting between levels 41 and 43.
6 m/s, intake airways 7 m/s, return airways 10 m/s, ventilation raises 16 m/s and
upcast shaft 17.
The two splits rejoin on the return to the
upcast shaft.
