This operation video presents a Huada horizontal core boring machine in a slate-mine context. The old description emphasizes convenient hoisting, simple operation and the ability to assemble different drill bits and rods.
Hoisting is only the first positioning step
Convenient lifting can help place the machine where quarry access is restricted. The base still needs a stable support and alignment with the planned hole. The archive does not give the available space, mounting method or completed hole direction.
Bit and rod selection
Customers can assemble drill bits and drill rods of different specifications according to the job. Those specifications are not listed on this page. Rock, required core diameter, target depth, available handling length and connection type should be supplied before a set is chosen.
Document the slate core
The title links the operation with slate, while the source also describes the machine for different stone mines. A setup chosen for slate should not be transferred to another rock without review.
Mark the target line, identify every bit and rod section, and record the measured hole and recovered core. Note feed interruptions and core condition rather than reporting only that operation was simple. These details would make the video useful as a drilling record without inventing diameter or output.
