Due to high mining height,there is a serious leakage of small coal gangue between the supports during the process of moving,resulting in high dust concentration.To solve the above problems,a flexible control device for leakage coal gangue between hydraulic supports has been developed.The main part of the device is manufactured by a specially selected stainless steel plus high-strength flexible,flame retardant,and anti-static textile-cored rubber,which is highly adaptable for deforma-tion with good sliding and anti-friction property.The device is installed between two hydraulic supports,covering the gap be-tween the side guard plates,guiding the inter-support coal gangue to the goaf side,avoiding dust accumulation during the coal gangue leakage process,and greatly reducing the workload of floating coal cleaning on the foot pedal.1t is of a wide ap-plication in similar coal mines with large mining height working face.
