摘要
概括了我国大倾角厚煤层开采状况,对放顶煤液压支架的结构特点及合理应用等进行了简单介绍,分析了放顶煤支架开采技术及方法。并有针对性地设计一种能适应较大倾角、满足较大采高并具有优良性能的新型液压支架。
In this article, the present mining condition of large-angle heavy coal seam is introduced, the structure feature of top -cave hydraulic support and how to use it rationally, then analyzes the mining technology and way of top-cave hydraulic support, further design a new kind of top-cave hydraulic support which has a larger angle , a taller shield height and good characteristics.
