Problems and suggestions on hoisting system of super deep vertical shaft sinking in China
FAN Wen-bo
Abstract：The status quo of China's domestic ultra-deep shaft hoisting equipment and projects was discussed, and compared with the situation of foreign super deep shaft hoisting system parameter configuration. Under the conditions of the existing domestic equipment and safety regulations, the difficulties faced by the ultra-deep vertical shaft sinking in raising the height, increasing the efficiency, and increasing the width of the machine drum are analyzed, and problems in the safety factor, maximum lifting speed, and winding layers of the steel wire rope are discussed. Further, proposals were made for the development and research directions of ultra-deep vertical shaft sinking.
