Coal Mine Underground Tunnel Drilling Rig

Product Introduction

A tunnel drilling rig, also known as a tunneling jumbo, is a hydraulic tunnel drilling rig that integrates multiple heavy hydraulic rock drills. It is specifically designed for rock tunnel drilling and underground drilling rig applications, making it the core equipment in the field of drill jumbo for tunnel construction. This type of tunnel boring equipment features a highly mobile crawler or tire-mounted chassis combined with a flexible boom positioning system, achieving exceptional drilling accuracy and efficiency in tunnel blast hole drill rig operations. It is widely used for drilling blast holes and systematic rock bolt holes. As a flagship product offered by a professional tunnel drilling rig manufacturer, it significantly increases excavation speed and reduces construction risks compared to traditional manual methods, making it an ideal choice to meet the demanding requirements of modern mining and tunneling projects for high-performance rock tunnel drilling equipment.3.

Application scenarios

1.Anchor drilling in engineering fields such as tunnels, subways, railways, and mines: particularly suitable for multi-angle drilling operations in tunnels, including horizontal, inclined, and vertical drilling. It offers fast drilling speed and high efficiency, capable of drilling 3 meters in 20 seconds.

2.Construction in complex rock formations and underground environments: when facing hard rock strata and complex underground conditions, tunnel drilling rigs must possess strong rock-breaking capabilities as well as precise and flexible all-position operation abilities to meet diverse construction requirements such as rock bolting, grouting, and pipe roofing within tunnels.

3.Different travel modes for different terrains: for example, crawler-type rigs are suitable for complex and uneven ground surfaces, while wheeled rigs facilitate rapid transfer within tunnels. These are applicable to various underground anchoring fields ranging from subways, culverts to underground parking lots.

4.Formation of ground reinforcement, cutoff walls, and advance support: the application of jet grouting rigs in tunnel construction is primarily reflected in ground reinforcement, the formation of cutoff walls, and advance support, providing strong technical support for the safety and smooth progress of tunnel construction.
