Mining Hydraulic Tunneling Drill Rig KJ311-K Makes Its Debut at Mining World Russia 2026 in Moscow

Powerful tunneling, high-efficiency rock drilling. On April 22, Mining World Russia 2026 grandly opens at Crocus Expo International Exhibition Centre in Moscow, where we present the KJ311-K Mining Hydraulic Tunneling Drill Rig at Booth No. D8007.

The KJ311-K featured at this exhibition is a medium-sized fully hydraulic tunneling drill rig designed for underground mine roadway excavation, specifically built for hard-rock roadway tunneling and mining preparation operations. The equipment features an impact-rotation hydraulic rock drilling system, paired with a four-wheel-drive articulated chassis, combining strong rock drilling capability, flexible maneuverability, and adaptability to complex underground working conditions, helping mines achieve safe and efficient production.

Product Features

1.Hydraulic rock drilling for efficient tunneling

Equipped with a high-efficiency hydraulic rock drilling system featuring impact-rotary combined drilling, enabling fast operation cycles and improved tunneling efficiency.

2.Universal boom for precise positioning

The feed beam supports 360° rotation and automatic leveling, facilitating rapid hole positioning and covering a wide range of drilling conditions; it enables lateral crosscutting and anchor bolt drilling while ensuring good visibility for the operator.

3.Articulated chassis for strong maneuverability

A well-balanced, powerful four-wheel-drive articulated chassis ensures flexible passage through narrow roadways.
