我矿在采矿工程中,配套使用FJY-25型圆盘式凿岩台架与YG80导轨式凿岩机钻凿垂直向上扇形中深炮孔。长期使用表明,该台架结构简单、体积小、重量轻、移动方便,但也发现该台架某些部件局部结构不够合理,致使某些部件工作可靠性较差(主要指1980年以前产品),影响凿岩效率。我们分析了这些结构缺陷,作了几点改进,取得了较好的效果。并修复了断裂的推进丝杠。现简述如下。 In our mine, we use FJY-25 type disc drilling rig and YG80 guide rock drilling machine to drill vertically upward and middle fan holes in the mine. Long-term use shows that the gantry is simple in structure, small in size, light in weight, and convenient to move. However, it has also been found that the partial structure of certain parts of the gantry is not reasonable enough, resulting in poor reliability of some components (mainly referring to products before 1980). Affects rock drilling efficiency. We analyzed these structural defects, made several improvements, and achieved good results. And repaired the broken propeller screw. This is briefly as follows.
