This video is a customer-use reference for a Huada horizontal core boring machine in a slate mine. That source is more specific than a general product page: it establishes the material and drilling application, but not the machine settings or result.
Why slate belongs in the project file
The core can help reveal bedding and local changes in the deposit. Its orientation and recovery condition matter, so the starting line and each recovered section should be marked. The old text does not report hole depth, diameter or core recovery.
What customer use can demonstrate
The recording can support the presence of the horizontal drill and the general operation where clearly visible. It does not by itself prove straightness, feed rate, bit life or suitability for every stone mine. Those outcomes require measurement.
Complete the field record
Identify the quarry, machine, bit, rods, target line and support arrangement before drilling. Record changes in feed and the measured finished hole, then photograph the ordered core sections.
The product family may serve other stone mines, but their rock and handling space need a new configuration. Keeping the slate evidence separate prevents a real customer application from being diluted into a universal equipment claim.
