Activity 7 – Carrying Out an Exploration Assignment – Level 2 Purpose: The team will practice

carrying out a realistic exploration assignment from the briefing through the underground exploration to the debriefing.

Type: Underground work problem

Activity 7 – Carrying Out an Exploration Assignment – Level 2 Materials:

Apparatus Team equipment:

Gas detectors Map and Mapboard Communication equipment Scaling bar

Fresh Air Base Equipment: Map Communication equipment

Placards (placed underground to indicate various conditions

Activity 7 – Carrying Out an Exploration Assignment – Level 2 Arrangements:

1. Arrange for the team to explore an area of the mine that they can cover in 2 hours.

2. Prepare copies of a map of the area to be explored.

3. At the starting point of the exploration, set up a simple fresh air base with a map and communication equipment.

Activity 7 – Carrying Out an Exploration Assignment – Level 2 Arrangements:

1. Arrange for the team to explore an area of the mine that they can cover in 2 hours.

2. Prepare copies of a map of the area to be explored.

3. At the starting point of the exploration, set up a simple fresh air base with a map and communication equipment.

Activity 7 – Carrying Out an Exploration Assignment – Level 2 Arrangements:

1. Prepare an exploration briefing (you can use the two samples provided below as a guide)

2. Place 3 or 4 placards in the area to be explored indicating various conditions; such as smoke, water, a piece of equipment burning, damage to ventilation control, a fall area, and so on.

3. Choose conditions that will coordinate with the situation you describe to the team in the briefing.

Activity 7 – Carrying Out an Exploration Assignment – Level 2 Description:

Have team or the benchman prepare the apparatus. When ready, the team should report to you with their apparatus and equipment

Give the teams mapman a map showing the area to be explored.

Activity 7 – Carrying Out an Exploration Assignment – Level 2 Description:

The captain should then lead the team to the fresh air base, have the team members check their equipment and get under O2.

When the team is ready, let them begin their assignment. You should accompany the team to observe their performance. The individuals staying at the fresh air base should stand by ready to perform their duties.

Debrief the team when they return.

Sample briefing for Multi-Level Mines

At 4 PM the dispatcher received a report from the underground hoist attendant at the #2 shaft, #9 level, of a possible rock burst. The hoist attendant heard aloud noise and felt a large gush of air in the underground hoist room. He said there was limited visibility in the area.

Sample briefing for Multi-Level Mines

All miners have been evacuated from the mine, and a fresh air base has been set up at the #2 shaft station, #9 level.

Your teams assignment is to explore and determine conditions on #9 level. Advance as far as you can, but be sure to return to the fresh air base no later than 2 hours after starting exploration.
