Abstract: Based on the design and construction of the Hongqinghe mine, the article comprehensively considers the scheme for mine well drilling from shaft elevation, main shaft equipment, hoist winch single power, auxiliary wellbore diameter, cage size, new freezing technology, and development plan layout. And the selection of lifting methods, discussed the main shaft lifting system and auxiliary shaft construction techniques and other new technologies, new processes, combined with mine resource conditions optimization and development program. The successful implementation and production of this mine has a strong reference for the design and construction of similar mines in China.
