RFQ:
1. What is drill casing in mining?
In underground mining, steel casing or steel pipe is used to line holes that have been bored or drilled for rising mains water, utility lines and paste fill, protecting the contents from damage and loss into open voids or broken ground.
2. How much PSI do I need for air tools?
Between 70 and 90 PSI
Most air tools require between 70 and 90 PSI. Any light-to-medium-duty air compressor can easily handle 90 PSI, but you always want the compressor to supply more flow than needed. Pro Tip: Always respect a PSI rating. If you don't supply enough air volume, the tool won't operate correctly.
3. Why is percussion drilling used?
Site examination using cable percussion drilling is a tried and true technique. The method of drilling makes it possible to insert casing inside the borehole to keep loose dirt from collapsing into it, enabling the borehole to be advanced to significant depths while still making good progress.
