针对当前深部复杂环境工作面液压支架群信息感知匮乏、数据分析不足、装备运行参数规律和数据模型难以支撑智能化开采及支护决策等问题，以淮南口孜东矿140502深部“三软”煤层大采高工作面为应用场景，通过构建深部工作面液压支架姿态监测系统，实现液压支架立柱压力和空间位姿的连续感知。基于工作面液压支架顶梁和底座横滚角数据，利用线段拟合方法实现工作面顶底板三维走向趋势实时可视化。基于工作面液压支架压力−位姿数据，建立液压支架压力−位姿数据映射关系和液压支架位姿计算模型。通过深部工作面支架压力和位姿的融合分析，揭示工作面采高、支架顶梁合力大小及合力作用点动态变化规律：相比于工作面两端液压支架，工作面中部液压支架采高最小，而工作面机尾的液压支架采高最大；工作面中部液压支架顶梁合力在大部分时间内都小于工作面两端液压支架顶梁合力；相比于工作面两端部支架，工作面中部支架顶梁合力作用点更偏向前立柱位置。

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.
