DRILL STEEL RETRIEVAL SLING
PATENT No. 2021/05544
DESCRIPTION
The “Drill Steel Retrieval Sling” is designed to arrest “stuck” drilling rods from the face after blasting and prevent associated damages to equip- ment. It is common practice to use drill steel for the drilling of shot holes, support holes and for securing objects.
PURPOSE
The purpose of drill steel retrieval sling is to prevent damage to equip- ment and plant by arresting the “stuck” drill steel during blasting opera- tions, including time and production delays the loose drill steel might cause to muck removal systems and during milling. The drill steel being retrieved will increase safety, efficiency, less tire damage while cleaning, delays in cleaning activities, conveyor belt damage, mitigate ore pass blockages, tip blockages, belt damage and plant delays due to a used drill steel getting into the system.
FEATURES
It is not uncommon for drill steel to get stuck during drilling and most of the time it takes great effort to remove the stuck drill steel in a conven- tional way. Mostly the stuck drill steel is blasted out when the face is blasted at the end of shift. Drill steels that get stuck are caused by inade- quate water pressure, inadequate air pressure, fragile ground conditions and excessively worn drill bits preventing the grid from bypassing the stem of the drill steel. Apart from the fact that drill steel is an expensive commodity, it can also cause damage when it is concealed in the muck. It can cause blocked ore passes due to obstruction(s), runaways if the drill steel comes between radial door and the chute whilst opening the door, conveyer-belt and tips damage, structural damage to and in the Plant and structural damage to service piping if blasted out.
The “Drill Steel Retrieval Sling” plays an important role in the following aspects of the removal of a drill steel:
Safety feature Removes the operator from the face area, prevents serious injury and/or death (where the necessary safety measures are adhered to as stipulated in the mining house induction training). Prevents major damage to equipment including but not limited to, structures, ventilation ducting, conveyor belts, support packs etc. caused by the drill steel shards in the blasted material and obstructions in the ore passes. Reduces standing time By preventing the risk of major damage to equipment, structures, convey- or belts, vehicles etc. downtime for repairs will be are limited. Cost saving mechanism In reducing downtime caused by the damage to structures and equip- ment, costs are saved which in turn prevents the mining house from over-spending which includes but is not limited to overtime of workers, repairs and replacement of damaged equipment and structures, etc.
