A "boomer machine" is a type of hydraulic drilling rig used primarily in tunneling, mining, and underground construction. It is often referred to as a "boom jumbo" or "drill jumbo" and is designed to drill blast holes in rock surfaces. It is a hydraulic drilling rig designed for precision and efficiency in rock excavation .

　　Uses of a Boomer Machine:

　　1. Tunnel Excavation – Used in underground tunneling projects, such as metro construction and road tunnels.

　　2. Mining Operations – Helps in drilling blast holes for rock fragmentation in mining sites.

　　3. Cavern Construction – Utilized for creating large underground spaces for storage or infrastructure.

　　4. Hydropower and Infrastructure Projects – Used in projects requiring large-scale rock drilling.

　　Primary Applications:

　　Boomer machines are primarily used in:

　　- Mining: For drilling blast holes in rock faces to prepare for explosives .

　　- Tunnel Construction: To create stable boreholes for ventilation, drainage, or structural support.

　　- Geotechnical Engineering: In projects requiring deep-core sampling or ground stabilization.

　　Advantages and Features:

　　- Automation: Modern Boomer models integrate automated controls to optimize drilling patterns and reduce human error.

　　- Durability: Built to withstand extreme conditions, including high temperatures and abrasive materials.

　　- Safety: Enhanced safety protocols minimize risks in hazardous environments.

　　These machines are typically equipped with multiple booms (arms) that hold drill rigs, allowing for efficient and precise drilling in hard rock environments. Leading manufacturers include Epiroc (formerly Atlas Copco), Sandvik, and Komatsu.
