薄-中厚煤层综采面自动化开采技术研究与实践

摘要

In order to improve a coal recovery rate of coal resources from a thin-medium thick seam,taking an unstable thin-medium thickseam in Huangling No.1 Mine as a study object,a matched technology plan of a high automatic fully-mechanized coal mining face was provided.With an organic integration of coal shearer control system,powered support electrohydraulic control system,coal mining face con-veying control system,three machine control system,pump station control system and power supply system,a centralized equipment control of the fully-mechanized coal mining face was realized by the monitoring and control center in the mining gateway and an automatic produc-tion of the coal mining process was realized.The site application results in Huangling No.1 Mine showed that,after using this technology, the average output per day was 6 600 t,and the efficiency was increased in the fully-mechanized coal mining face.%为提高薄-中厚煤层煤炭资源采出率，以黄陵一号煤矿薄-中厚且不稳定煤层为研究对象，提出了高度自动化综采工作面配套技术方案，通过将采煤机控制系统、支架电液控制系统、“三机”控制系统、泵站控制系统及供电系统有机融合，实现在巷道监控中心对综采工作面设备的集中控制，实现了采煤全过程的自动化生产。在黄陵一号煤矿的现场应用结果表明：采用该技术后，平均日产量可达6600 t，综采工作面实现了减人提效。
