兖州矿务局东滩煤矿、郑州煤矿机械厂、煤科总院南京所共同研制的ATY—2500反井钻机,可用于煤炭、冶金等矿山钻扩直径达3m的反井,是国内目前最大的机型。它经过在东滩矿井下的工业性试验后,中国统配煤矿总公司技术发展局已于1992年12月主持会议通过了技术鉴定。这种钻机的主机采用了国际上先进的两柱三缸结构,在主机的下面打了牢固的混凝土基础,钻机工作平稳,承载能力大,鼓形齿浮动式的驱动头能够防止减速箱承受由钻
ATY-2500 anti-rig drilling machine co-developed by Yanzhou Mining Administration Dongtan Coal Mine, Zhengzhou Coal Mine Machinery Factory and Nanjing Coal Research Institute Nanjing can be used to drill and expand the anti-well with the diameter of 3m in coal and metallurgical mines, etc., which is the largest in China at present model. After it passed the industrial test in Dongtan mine, the technical development bureau of China General Coal Mine Corporation passed the technical appraisal at the presiding meeting held in December 1992. The host of this drilling rig adopts the internationally advanced two-column and three-cylinder structure, and fights a solid concrete foundation under the mainframe. The drilling rig works smoothly and has a large carrying capacity. The drum-shaped tooth-floating driving head can prevent the gearbox from being subjected to Drill
