⚙ Underground Development
Mining Tools Used in Tunnel Excavation and Underground Development
Tunnel excavation and underground development demand mining tools that are powerful, reliable, and built to perform in the most challenging conditions. Whether you are breaking through concrete, brick, or hard rock formations, having the right pneumatic pick hammer and Hydraulic Drifter can mean the difference between efficient progress and costly downtime. At Mindrill, we supply professional-grade pneumatic tools engineered for exactly these environments.
In this blog, we explore the key mining tools used in tunnel excavation and underground development — and highlight four of Mindrill's most trusted pick hammers, each designed to handle the rigors of underground work with precision and durability.
The Role of Pick Hammers in Underground Mining
Why the Right Tool Matters Underground
In tunnel excavation and underground development projects, pick hammers are among the most essential handheld tools on site. They are used for breaking, chipping, and scaling rock and concrete surfaces in confined spaces where larger machinery cannot reach. A good pick hammer must deliver consistent impact force, minimize operator fatigue, and withstand continuous use in dusty, damp underground environments.
Mindrill's pneumatic pick hammers are designed with exactly these demands in mind — featuring air cushioning systems, two-step triggers, ergonomic handles, and quick-change tool retention systems that keep productivity high and downtime low.

Choosing the Right Tool
Matching the Hammer to the Application
Selecting the right pick hammer depends on the hardness of the material, the workspace, and the required impact rate. For lighter breaking tasks or tighter spaces, the compact MPH33 at 5.5 kg and 2000 BPM offers excellent maneuverability. For heavier-duty tunnel scaling and concrete demolition, the MPH09S and MPH09 provide robust performance with superior vibration control. For maximum impact rate in professional settings, the MPH37 at 2650 BPM is the go-to choice for experienced tradesmen.
All four models share Mindrill's commitment to operator comfort, featuring ergonomic handles, air cushioning systems, and kick-latch retainers for rapid chisel changes — keeping your crew productive throughout long underground shifts.
