  • 摘要: 针对10 m超大采高综采工作面采场空间大、装备尺度大、围岩扰动强、采支运供多系统耦合紧密等特点,以曹家滩122104工作面为工程对象,开展多源感知与装备协同调控技术研究。构建由感知层、数据层、决策层和执行层组成的总体架构,提出液压支架倾角、压力、行程与视觉信息融合的综合工况感知方法,实现支架姿态、支护高度及承载状态的实时监测。建立采煤机截割状态、刮板输送机煤流负荷、支架跟机动作及供液供电状态之间的协同调控逻辑,并集成设备健康管理与多源数据融合分析平台,实现主要装备状态的在线监测与预警。煤流状态通过非接触式视频识别方法进行测量,平均识别准确率达到92.3%,支持采煤机牵引速度、刮板输送机运行状态和运输系统负荷的智能调控。工程实践表明,该系统能够在10 m级超大采高工作面实现高效、安全和智能化开采,保障了设备群协同运行和采运平衡,为厚煤层及中厚煤层矿区的高效智能开采提供了可靠技术支撑。

     

    Abstract: Aiming at the characteristics of large stope space, large equipment scale, strong surrounding rock disturbance and close coupling of multi-system of mining-supporting-transportation-supply in 10 m super-large mining height fully-mechanized working face, the 122104 working face of Caojiatan is taken as the engineering object to carry out the research on multi-source perception and equipment coordinated control technology. The overall architecture composed of perception layer, data layer, decision-making layer and execution layer is constructed. A comprehensive working condition perception method of hydraulic support inclination angle, pressure, stroke and visual information fusion is proposed to realize real-time monitoring of support attitude, support height and bearing state. The coordinated control logic between the cutting state of the shearer, the coal flow load of the scraper conveyor, the movement of the support and the power supply state of the liquid supply is established, and the equipment health management and multi-source data fusion analysis platform are integrated to realize the online monitoring and early warning of the main equipment state. The coal flow state is measured by non-contact video recognition method, and the average recognition accuracy is 92.3%, which supports the intelligent control of shearer traction speed, scraper conveyor running state and transportation system load. The engineering practice shows that the system can realize efficient, safe and intelligent mining in 10 m super large mining height working face, ensure the coordinated operation of equipment group and the balance of mining and transportation, and provide reliable technical support for efficient and intelligent mining in thick coal seam and medium thick coal seam mining area.
