薄煤层刨煤机工作面关键设备适应性改造技术研究

Study on adaptability enhancement of critical equipment for coal-plough mining face in thin seam

根据刨煤机工作面原配套设备在生产中出现的端头支架移架速度慢、基本支架扎底严重、对顶板适应性差、刨煤机断链频繁、刮板输送机重载启动烧电机等诸多问题,分别对液压支架、刨煤机的结构和控制进行了一系列适应性技术改造。

Aimed at the problems of original equipments for the coal-plough mining face during the production, such as low moving velocity of end supports, serious underframe sinking, bad adaptability to the roof, frequent chain scission of coal-plough, and motor damaged when heavy-loading startup of conveyer, a series of techniques were carried out to enhance the adaptability of structure and control of hydraulic supports and coal-plough, suggesting good application effect and high value of popularization.
