摘要

摘要: 综采工作面智能化是煤矿智能化的关键环节，液压支架状态感知与分析是综采工作面智能化的前提和智能控制的基础。液压支架压力和位姿是液压支架能够直接监测的关键状态数据，二者进行融合分析是液压支架智能控制和智能执行的依据。以液压支架压力和位姿为研究对象，介绍了智能化综采工作面状态感知架构。从液压支架受力和上覆岩层矿压2个角度总结了液压支架压力感知与分析技术现状，指出目前基于大数据的矿压分析尚未应用、工作面矿压与巷道压力数据未实现同步测量、未实现整个采场的全面数据分析、对超前液压支架的关注度不够。阐述了液压支架位姿感知原理和方法，总结了现有液压支架位姿分析方法。分析了液压支架压力−位姿融合分析的必要性，总结了现有的液压支架压力−位姿融合分析方法。展望了综采工作面液压支架状态感知与分析技术的发展趋势，即深入研究大数据技术、多维数据融合感知与分析技术、数字孪生技术在液压支架状态感知与分析中的应用，以实现液压支架状态数据精细化分析、智能控制与决策。

Abstract: The intelligence of fully mechanized working face is a key link in the intelligence of coal mines. The perception and analysis of hydraulic support state is the premise and foundation of intelligent control of fully mechanized working face. The pressure and posture of hydraulic supports are key state data that can be directly monitored. The fusion analysis of the two is the basis for intelligent control and execution of hydraulic supports. Taking the pressure and posture of hydraulic supports as the research object, an state perception architecture for intelligent fully mechanized working face is introduced. The current status of hydraulic support pressure perception and analysis technology is summarized from two perspectives: hydraulic support stress and overlying rock pressure. It is pointed out that the current big data based mine pressure analysis has not been applied, the mine pressure and roadway pressure data at the working face have not been synchronously measured, the full face data analysis of the entire mining area has not been achieved, and there is insufficient attention paid to advanced hydraulic support. The paper elaborates on the principles and methods of hydraulic support posture perception, and summarizes the existing hydraulic support posture analysis methods. The necessity of pressure-posture fusion analysis for hydraulic support is analyzed. The existing methods for pressure-posture fusion analysis of hydraulic supports are summarized. The paper explores the development trend of hydraulic support state perception and analysis technology in fully mechanized working face. It is suggested to do in-depth research on big data technology, multidimensional data fusion perception and analysis technology, and digital twin technology in the application of hydraulic support state perception and analysis, so as to achieve the precise analysis of hydraulic support state data, intelligent control and decision-making.
