液压支架跟机过程推溜-移架能耗建模与分析OA

Coal mining is a high-energy industry.Intelligent mining pursues both efficiency and low-carbon operation.The conveyor pushing and support moving process of hydraulic supports is the main energy-consumption stage in following shearer process.It represents a key issue for energy optimization.To address this issue,a mathematical energy-consumption model for hydraulic supports following shearer process is established.It uses response surface and correlation analyses to examine the effects of shearer traction speed,pushing-jack inlet pressure,flow rates of leg raising and lowering,and inlet-return pressure.It also analyzes single-factor effects and parameter interactions.A case study on the ZY21000/38/82D hydraulic support in a Shaanxi coal mine shows that traction speed is the dominant factor and has a nonlinear negative relation with both conveyor pushing and support moving energy-consumption.The pushing-jack inlet pressure,leg inlet pressure,and leg raising and lowering flow rates each show linear positive relations with conveyor pushing energy-consumption.The leg return pressure shows a linear negative relation with conveyor pushing energy consumption.Parameter interactions have a significant influence on total energy-consumption.This energy-consumption model provides a theoretical foundation for optimizing hydraulic support parameter configurations.It helps reduce following shearer consumption and promotes green low-carbon transformation in the coal mining industry.
