特大采高液压支架增压增力复合护帮机构的研究

Research on Complex Side Wall Protection Mechanism with Pressure and Force Increasing for Large Mining Height Support

分析了特大采高液压支架护帮作用机理,提出了特大采高支架增压增力复合护帮机构的特点、工作原理、创新点及与现有设备的对比,特别提出在7 m以上大采高支架增压增力复合护帮机构在支架防护方面的使用效果。

This thesis analyses mechanism of side wall protection of super large mining height, puts forward the characters, working principles, innovative points and the comparison of current apparatus of composite structure of side wall protection with increasing pressure and force of the hydraulic support with super large mining height, especially the shielding effect of side wall protection with increasing pressure and force of the 7-meter-high hydraulic support with large mining height.
