Questions and Answers
What are the potential hazards associated with truck transport and borehole feed in mine backfilling?
Variable transport distances to boreholes, variable fill character due to variable mix times, and lack of time control to stope delivery for QC.
How can the potential hazard of blockage of borehole due to freezing in cold climates be controlled for surface pipeline transport from plant?
Insulate the pipeline leading from plant to borehole, provide heated covers, and climate protection.
What are the two methods of backfill transport and distribution system mentioned in the text?
Pipeline transport of hydraulic (slurry) or paste fill, and batch transport of paste fill using cement mix trucks.
