specifically intended for construction the of Skipo-Kletevaya mineshaft . According to Andrey Vyatkin , Chief Designer of Materials Handling and Crushing Equipment , the mobile machine was designed in compliance with the customer requirements & consists of pre-assembled individual transportable units . Such a design allows for reduced labour intensity , and lower shaft construction and mounting costs . Commissioning of the mine hoist 2.6 x 2.2 will speed up shaft sinking to 55-60 m per month .
Uralmashplant will also manufacture two more mine hoists machines for the Skipo- Kletevaya mineshaft at the Novo-Uchalinsky copper-zinc deposit . “ The first one will be used for ore hoisting , and the second one will be used to lower and lift employees , materials , rock , etc ,” comments Ilias Akhmedianov , Chief Engineer of Uchalinsky GOK JSC .
The underground mine construction at Novo-Uchalinsky deposit is a strategic project of UMMC included in the list of high-priority projects of the Republic of Bashkortostan . Novo- Uchalinsky ore deposit reserves amount to approximately 116 Mt .
CITIC HIC remains China market innovator
Luoyang-based CITIC HIC is the leading manufacturer for designing and manufacturing mining hoists in China . Since 1958 it has supplied well over 8,000 of various hoist types in which its single-rope mine drum hoist accounts for 70 % share of the domestic market and its multirope hoist 80 %. One of the original coal mine hoists supplied in 1958 operated until 2007 .
The CITIC range in diameter includes 1.3-7 m floor-mounted and tower multi-rope friction hoists ; 1.6-7.6 m single / double-drum singlerope mine drum hoists ; 1.6-4 m electric antiexplosion hoists ( winch ); 1.6-4 m hydraulic antiexplosion hoists ( winch ); and 2.8-5.5 m sinking hoists . CITIC told IM it has manufactured over 170 large hoists since 1994 , including friction gear or reel of diameter 4.5 m and above .
“ CITIC has accumulated knowledge over many years experience in designing and manufacturing hoists , keeping abreast of the latest technology developments for the international markets and contributing to several national scientific research and development projects , such as on large hoist localisation research , as well as leading technical advancements of hoist design .”
In the 2010s and 2020s , more than 600 hoists have been supplied in China and for export , including the largest single rope winding mine hoist inside China , a 2JK-6 × 2.5 . Others have included a JKM-4.5 × 6PIII ( max static tension 1,131 kN ; max static tension difference 303 kN ; max hoisting speed 12 m / s ; motor power 4,400 kW ) for the main shaft of Nonferrous Donggua Mountain in Tongling ( copper ); a JKM-4.5 × 4PIII ( max static tension 990 kN ; max static tension difference 210 kN ; max hoisting speed 9.9 m / s ; motor power 1,800 kW ) for the Huize lead-zinc mine in Yunnan ; and for the main shaft of Huainan Mining Bureau ’ s Guqiao coal mine , a JKMD-5 × 4PIII ( max static tension 1,200 kN ; max static tension difference 440 kN ; max hoisting speed 16 m / s ; and motor power 5,300 kW ). For the main shaft of Zhangji Coal Mine of Huainan Mining Bureau CITIC supplied a JKMD-5.7 × 4PIV ( max static tension 1,500 kN ; max static tension difference 440 kN ; max hoisting speed 14 m / s ; motor power : 3,000 kW × 2 ). For the auxiliary shaft of Ganshu Hetaoyu coal mine CITIC supplied a JKMD-6.2x4PIII ( max static tension 1,700 kN ; max static tension difference 340 kN ; max hoisting speed 11.3 m / s ; and motor power 3,000 kW ). For the main shaft of Zambia Chambishi copper mine , a JKMD-5.7 × 4PIII ( max static tension 1,530 kN ; max static tension difference 420 kN ; max hoisting speed 13 m / s ; motor power : 6,300 kW ). For the main shaft of Shougang Luannan Macheng mine , a JKM- 5.5 × 6PIV ( max static tension 1,824.8 kN ; max
