Underground pneumatic drilling review
For manual pneumatic short-hole work, first decide how the drill will be supported and controlled. Then review the rock drill, air leg or hand-held setup, drill steel, bit, air, lubrication and water as one system.
Verified scope: confined headings, supported air-leg drilling and portable hand-held pneumatic short-hole tasks. The final written quotation confirms the exact configuration and supply scope.
Start With the Heading and Hole Task
The site team defines the drilling and safety task. For an equipment review, provide the heading dimensions and access, working direction, target hole diameter and depth, rock and water conditions, and whether supported feed is required. Also record the air and water available at the work area—not only the compressor’s nominal rating.
Heading and access
Show the face, service space, movement restrictions and where the operator, drill and hoses must work.
Hole and direction
State diameter, depth, orientation and the support method already defined for the task.
Rock and water
Describe abrasivity, fractures, mixed zones, visible water and the intended dry or wet drilling arrangement.
Site services
Provide tool-inlet pressure and flow where known, hose internal diameter and length, fittings, lubrication and water-flushing details.
Choose the Starting Path
When supported feed is part of the defined task
Review the exact drill and air-leg identities, mounting interface, working direction, H22 steel and bit, plus air, oil and water conditions. A YT drill and an FT air leg are not interchangeable by family name alone.
When portable control is the defined method
Review the task, direction, shank, drill steel, bit, air and flushing. A hand-held drill is not assumed to replace an air-leg drill at the same depth, duty or production requirement.
When the task is outside the verified public path
Upward or vertical work, unsupported overhead conditions, specialist stoper work, long-hole or mechanized systems, and unknown legacy equipment require identification and site review before a product path is proposed.
Review the Complete Working Chain
Site air → hose and coupling → line oiler and water → rock drill plus support method → drill steel → bit → hole.
Pressure and flow must be considered at the tool inlet under operating conditions. Hose length, internal diameter, fittings, leakage and simultaneous tools can change what reaches the drill. Lubrication, water and flushing are part of the chain, not accessories to check after the drill body is selected.
Interfaces and Identity Gates
- Exact drill model and suffix: similar names do not prove the same internal or mounting configuration. Y24 and YT24 are different identities.
- Air-leg model and interface: record the full suffix, connection and dimensions instead of choosing from appearance.
- Shank and drill steel: H22 × 108 is a reference to verify, not proof that the drill, steel and air leg form a compatible system.
- Taper and bit: confirm 11° where applicable, diameter, profile, rod identity and flushing. One taper label is not a complete compatibility decision.
- Unknown legacy equipment: send the nameplate, complete-machine and interface photos for an identification inquiry before requesting substitution.
Current Product-Family Paths
Air-Leg Rock Drills
Compare the current family, then confirm the exact drill suffix, air-leg interface, shank and site services.
Hand-Held Pneumatic Rock Drills
Use this path for portable pneumatic short-hole inquiries, with the job and working direction clearly stated.
Current Inquiry Starting Points
The links below are separate current inquiry pages. They are not a pre-confirmed combination.
Send the task, working direction, shank, air and flushing information.
Where This Page Stops
Mechanized long-hole production, drill jumbos, hydraulic systems, raise boring, unsupported overhead work, ground-support design, blast design and unknown legacy substitutions are outside this page’s verified supply path. They require the responsible site engineer, machine maker, controlled drawings or a separate manual technical review. This page does not provide a safety approval, productivity guarantee or final configuration.
Use the Guides for Setup and Identification
Send the Underground Inputs for Review
Include the mine or tunnel task, heading dimensions, working direction, hole diameter and depth, rock and water conditions, access limits, required support method, drill and air-leg suffixes if known, shank/steel/taper/bit details, tool-inlet air and hose arrangement, lubrication and wet/dry drilling requirement, expected duty, quantity and destination. Nameplate, interface and complete-machine photos are especially useful when the exact identity is unknown.
The visible review is for pneumatic short-hole drilling. The historical RFQ parameter preserves attribution; it does not expand this page into a complete underground-mining system.
