A Stoper drill machine takes its starting position below a planned blasthole collar. On YSP45, a long feed section extends beneath the percussion unit, pressing the cutting assembly towards upper rock. Compressed air drives both impact and advance. This upright geometry follows a steep bore line through an underground opening. It is useful where work must reach above the usual face-drilling position. Before installation, crews need room for shortened equipment, its extension and the intended drilling steel. Those dimensions establish whether a proposed position is physically accessible. As the hole progresses, upward thrust maintains cutting contact while the operator controls the working action.

Product Advantages
Interchangeable wedge arrangements let the Stoper drill machine accommodate the positioning provisions of its design.
Retraction provides a defined configuration for moving equipment between working locations.
Published pressure points give our enquiry discussion a concrete basis. We can relate those entries to the proposed underground utilities before agreeing associated accessories.
Main Applications
• A Stoper drill machine prepares fan-shaped hole patterns in stopes where individual bore directions spread across upper rock.
• Parallel upward holes serve layouts that retain a common drilling direction.
• Raises and shafts require steep drilling appropriate to their excavation plan.
• Tunnel-crown work places boring activity over the working area, subject to suitable clearance.
FAQ
Q: Does feed travel equal maximum attainable hole depth?
A: No. Travel measures extension; drilling tools and the job plan determine the bore.
Q: Can a favorable hardness rating guarantee rapid penetration?
A: No. Actual rock behavior and bit condition also matter.
Q: May this pneumatic mechanism run without lubrication?
A: No. Include a functioning line oiler in its operating setup. Oil carried in compressed air reaches moving internal surfaces; select lubricant and its delivery arrangement according to operating instructions for that particular model and its application.
