New type hoisting system of mine shaft sinking applied to shaft construction in coal mine

in order to overcome the insuificient production capacity of the available hoistng equipment fr the mine shaft sinking in a large dianeter deep mine shaft constucion an a long ock waste remov al time shorage restriced the safety an high etficient constuction in the mine , new mine shaft sinking equipment shouldbe developed as required to improve the construction speed ofthe mine saft. A new set of the mine hoisting system fo mine shar s inking was reearched and developed.incucing 6 m3.7 m3 and & m 3 bucket,G13,G15,G18,G21 and G25 hook.JKZ-5×3 .1 and 2JZ-5× 2.65 hister and 3.5 m and 4.0 m head sheave. The new hoistingsystem was successiul appied to the construcion ste ofthe main shaft in Yingoanhao Mine. The resulis showed ht the new hoistng system could highly speed up the waste rock removal and a comprehensive month heading rate of10 m was realzed.The mine construction speed was increased and the mineconstoution was completed 32 days earlier than the scheduled period with an obvious economic benefit.
