Development and Application of ZY6400/25/53 Two-leg High Cutting Hydraulic Shield Supports
We have independent developed ZY6400/25/53 two-leg high cutting hydraulic shield supports firstly,which width was 1.5 m could adapt to much complicated geological conditions,reduced the hydraulic support and accessories costs,and solved the problems of supports stability efficiently.Industrial tests showed that the supports application were successful and effective.We realize the high efficient production,the average yield reach to the level of 10000 t/d,if mine system have working conditions,the coalface have the ability produce 5Mt coal annually.This hydraulic support greatly improve the coal resources mining rate,broaden the application range of the high cutting fully mechanized mining technology in China,and led the upgrade of mechanized equipment.
