Abstract：Aiming at the challenges of slow dismantlement of hydraulic supports in fully mechanized top-coal caving face,subsidence of hydraulic support base plate during steering,and tilting of supports,the comprehensive methods including on-site investigation,numerical simulation,and theoretical analysis methods were adopted to develop the safe dismantlement platform of hydraulic supports for fully mechanized top-coal caving face.The main structure and operating process of the retraction platform were analyzed,and the stress and displacement characteristics during the process between hydraulic supports and dismantlement platform were simulated and studied.Field industrial tests were conducted on typical top-coal caving face in Shuiyu Coal Mine,and the application effect was favorable,providing a certain reference for safe dismantlement of hydraulic supports in similar face.
