Runs of Material Incidents & Categories2002-2011

Total Incidents - 100

* Runs of Muck Underground - 56 Incidents* Incidents at Loading Pockets - 14 Incidents* Muck Falling Down the Shaft - 30 Incidents

4

Causes of Runs of Water Underground

• Overflowing sumps• Punctured fill barricades• Dust suppression sprays• Spring run off• Known wet passes• Leaking fill lines• Seepage from near by pits in spring• Broken water lines

5

Causes of Run of Muck Underground

• Runs of water into ore pass• Dumping wet sand fill into ore passes• Impounded water in raise bore holes being reamed• Malfunctioning chute gates• Adding water to muck in passes that was sticking due to the

presence of wet muck and fines• Failing to pull the pass for a number of days

6

Causes of Muck Down the Shaft

• Operator not following proper procedure• Faulty measuring device• Clearing a hung up rock• Manually activating the solenoid of the discharge door in the wrong

compartment by the skip tender• Bin probe not reset after repairs• Defective relay put skip too low • Hopper door staying open• Arc gate not closing• Transfer car cylinder failure• Catch pit failure

7

Prevention of Incidents Relating to Water or Slime Material from Entering Passes

• Work should be stopped immediately• A supervisor and all workers in the vicinity should be notified• All affected work areas should be signed, barricaded against entry and

evacuated• The source of the water must be found and stopped as soon as possible• All drain holes in a mine must be checked and cleaned on a regular basis• A procedure to safely remove a build up of water should be established

and reviewed with the workers involved • A general policy , backed up with training and safety meetings, about managing the flow of water through a mine. Water used for washing and dust control must be monitored and controlled

8

Run of Materials Compliance & the IRSRegulation 854

Sec. 87 – Water Accumulation(1) A workplace in an underground mine shall,• be kept free of the accumulation of water• have a drainage system to pump excess water to a pumping system

capable of pumping water to surface for disposal(2) Where accumulations of water are likely to be present,• A borehole shall be drilled at least six meters ahead of the working • face to protect against a sudden breakthrough of the water, and• Precautions shall be taken to control the flow of water

(3) A positive displacement water pump shall be equipped with a relief valve or system

(4) Precautions shall be taken to guard against an accumulation of water in a chute or raise where the material may block drainage
