Lesson 3 – Diamond Drilling Procedure

1. EXAMINE GAS MEASURING INSTRUMENT

1.1 Check the number to ensure the allocated instrument is taken.
1.2 Examine the instrument visually for any obvious damages.
1.3 Check the battery to see if it is adequately charged.
1.4 Check the calibration at the testing point. The reading must correspond with the flammable gas mixture as displayed at the testing point.
1.5 When satisfied that the gas measuring instrument is in order the operator must sign for the instrument
1.6 A continuous measuring device should be used if available.

2. TEST FOR FLAMMABLE GAS

2.1 At the beginning of the shift:
2.1.1 When arriving at the diamond drill cubby, test for flammable gas in the through ventilation.
2.1.2 Test at all cavities in the hanging wall of the cubby.
2.1.3 Test the general atmosphere, covering the entire cubby.
2.1.4 Test the area within 0,5metre radius around the hole.
2.1.5 Test at the collar of the hole or in the case where the rods were not extracted, test at the core stopper. (Above and back end of drill string)

2.2 Tests during Drilling Operations
2.2.1 When water is intersected.
2.2.2 When suspected that flammable gas was intersected (Air bubbles are observed in drilling water in return flow).
2.2.3 When a loss of drilling water is experienced.
2.2.4 When pulling rods, examine after every tenth rod, except when a continuous gas measuring instrument is in place.
2.2.5 Test at core stopper behind the machine for gas prior to inserting an additional rod.
2.2.6 At hourly intervals.
2.2.7 Direct flow drilling.
2.2.8 Reverse flow drilling.

3. REVERSE FLOW:

3.1 When using a continuous gas measuring instrument, the instrument must be placed at the highest possible area where methane is likely to accumulate against the hanging wall, above the core stopper.

3.2 Direct flow
3.2.1 Test at the collar of the hole, drilling cock or casing pipe every time a rod is being inserted or removed.

3.3 Flammable gas is detected, and evacuation procedures.
3.3.1 Maintain ventilation in a normal manner in accordance with the mine‟s standard instructions.
3.3.2 Open compressed air onto the hole to dilute the flammable gas (the air hose should not be equipped with a tailpiece at the discharge point).
3.3.3 Withdraw all persons to a point of through ventilation, free from any flammable gas.
3.3.4 Post a guard in through ventilation, free from any flammable gas to prevent inadvertent entry of persons.
3.3.5 Report the presence of flammable gas as soon as possible to a Mining Official and Environment Control Department.
3.3.6 The person reported to must sign the operator‟s notebook as proof of acknowledgement.
3.3.7 Follow up if report has received the attention of Senior Mine officials.
3.3.8 If no Mining official is available, barricade the area and mark the barricade properly with the wording “DANGER- FLAMMABLE GAS – NO ENTRY”.

At the end of the shift
Return the flammable gas- measuring instrument to the lamp room.
