Design Characteristics and Optimization Measures of ZY4800/11/22 Large Dip Angle Hydraulic Support
The average dip angle of the 1103 fully mechanized mining face in Dongxingtai Coal Mine,Baicheng,Xinjiang is 45°,and the maximum dip angle can reach 50°.Based on the occurrence conditions and characteristics of this coal seam,a ZY4800/11/22 large dip angle hydraulic support is designed.This paper elaborates on the definition of dip angle hydraulic support and the design characteristics of ZY4800/11/22 dip angle hydraulic support.According to the overall layout requirements of the working face,the hydraulic support for the head and tail of the working face is optimized and designed,providing an effective way and method for equipment matching and mining technology in similar coal seam mining.
