Design and Application Analysis of Hydraulic Support Retraction Device in Fully Mechanized Mining Face
There are many hydraulic supports in the coal mining face,and most of these supports account for a large volume and have a large weight,which has a direct impact on the efficiency of retraction.In the current hydraulic support retraction operation,adopt the dismantling mode of winch and pulley combination,this traditional disassembly and assembly mode,need to disassemble and assemble winch many times,cause the overall dismantling efficiency is very low,can not be adapted with the modern mining speed,can not reach the mining demand of the current working face,so the traditional hydraulic direct retraction process has been unable to carry out the working face replacement production,and needs to be redesigned to meet the mining requirements of the current working face.Taking a working face as an example,this paper summarizes the traditional hydraulic support retraction process,analyzes the current design process of hydraulic support retraction device,and conducts experiments at the same time,and finds that the retraction efficiency is signif-icantly higher,and finally discusses the relevant measures of support retraction safety technology.
