Description

TECHNICAL FIELD

[0003] However, the traditional roof breaking device is not equipped with a targeted dynamic protection mechanism, or a fixed baffle is used. When the roof breaking column swings to adjust the roof breaking angle, the fixed baffle cannot follow synchronously, causing the gangue (rock fragments, rock blocks) splashed in the goaf to directly impact the standby hydraulic system and valve pipeline. According to statistics, the damage to the hydraulic column and the rupture of the pipeline caused by the impact of the gangue account for more than 37% of the reasons for the downtime maintenance of underground equipment, which not only affects the work efficiency but also directly threatens the safety of personnel.
