CYTC89Y2 underground remote-control production drilling rig, a high-performance hydraulic long hole drill rig and China production drilling rig, is designed for middle to large-vein tunneling and mining applications. As a versatile tunnel drilling jumbo, it is equipped with a HYG top-hammer hydraulic drilling machine, capable of handling hole diameters from 51 to 89 (102) mm, and a flexible positioning unit that adapts to various production drilling methods—including tasks related to rock bolt installation.

This drill rig offers an extensive coverage area, with a feed dump range of +200 forward and -800 backward, enabling 360° ring drilling of parallel holes upwards, downwards, and on side walls. It also features a rod handling system (RHS) with a maximum capacity of 32 rods in the rod carousel, enhancing operational efficiency.

The CYTC89Y2 production drilling rig, functioning as a reliable tunnel drilling jumbo, is a key equipment for the sublevel caving method. A notable application is seen in an iron mine, where the rig is used to drill 76 mm diameter fan-shaped deep holes. After adopting the CYTC89Y2, significant improvements were observed: drilling precision was markedly enhanced, rock drilling speed increased, overall production efficiency saw a substantial boost, and the blasting effect of medium and deep holes was improved. As a leading drill rig in its class, it seamlessly integrates the capabilities of a hydraulic long hole drill rig and tunnel drilling jumbo, solidifying its position as a top-tier China production drilling rig for demanding mining and tunneling operations.
