Study on the Dynamic Characteristics of Hydraulic Combined Support for Comprehensive Excavation Roadway in Coal Mine
In order to improve the safety of underground operations in coal mines,a method of analysing the dynamic characteristics of hydraulic combined support for comprehensive roadway excavation in coal mines is introduced with ZBE250 hydraulic support as the research object.Firstly,based on the specification size and material properties of the hydraulic support,a finite element model of the hydraulic support is constructed,and then based on this,the transient dynamic characteristics of the support are simulated and analysed under different working conditions,so as to find out the defects of the hydraulic combination support,provide support for the optimal design of the hydraulic combination support,and improve the safety of the underground operation of coal mines.
