深部复杂环境工作面液压支架压力-位姿融合分析技术
Hydraulic support pressure-posture fusion analysis technology for deep complex environment working faces
摘要
Abstract
In response to the challenges of limited information perception,insufficient data analysis,and the difficulty in supporting intelligent mining and support decision-making with equipment operational parameters and data models in deep complex environment working faces,this study focused on the 140502 deep"three-soft"coal seam high mining working face at the Huainan Kouzidong Mine.A hydraulic support posture monitoring system was developed to enable continuous monitoring of the hydraulic support leg pressure and spatial posture.By analyzing the roll angle data of the hydraulic top beam and base,a line segment fitting method was employed to visualize the three-dimensional trend of the roof and floor of the working face in real-time.Based on the hydraulic support pressure-posture data,the study established a mapping relationship between hydraulic support pressure and posture and developed a hydraulic support posture calculation model.Through the fusion analysis of the hydraulic support pressure and posture in the deep working face,the study revealed the dynamic change patterns of mining height,total force on the hydraulic top beam,and the point of application of the total force.Compared to the hydraulic supports at both ends of the working face,the hydraulic support in the middle had the smallest mining height,while the hydraulic support at the tail had the largest mining height.The total force on the hydraulic top beam in the middle of the working face was smaller than that at both ends for most of the time.Furthermore,the point of application of the total force on the hydraulic top beam in the middle of the working face was more inclined toward the front column position compared to the supports at the ends.关键词
