Activity 3 Interpreting a Ventilation Map

• Level 1
• Purpose The team will develop skill in reading
  and interpreting level or section ventilation
  maps.
• Type Classroom discussion

4
Activity 3 Interpreting a Ventilation Map

• Level or section map showing ventilation (use one
  from your mine or a sister mine)

5
Activity 3 Interpreting a Ventilation Map

• Description
• Have team members describe how the air is coursed
  through the level or section, discussing the use
  of regulators and auxiliary fans and tubing (if
  used). Be sure to have them describe how air gets
  to and from the mining areas and into the exhaust
  air.

6
Activity 3 Interpreting a Ventilation Map

• Description
• Then, after this is done, add a problem to the
  map that would affect ventilation and have the
  team members describe how this would change the
  ventilation. This problem could be
• An auxiliary fan thats down, or tubing thats
  down
• A bulkhead thats blown out
• A ground fall that has obstructed a particular
  area
• A mine door that was left open or that failed to
  close automatically

7
Activity 3 Interpreting a Ventilation Map

• Evaluation
• Use the following checklist to aid you in
  evaluating each team members performance. Be sure
  to list and discuss any problems the team
  encountered.

Activity 4 Using an Anemometer Underground
Level 2

• Purpose The team will develop skill in taking
  air measurements with an anemometer and practice
  working together as a team while under O2.
• Type Underground work problem
• Materials
• Anemometer
• Smoke tube and stopwatch
• Tape measure
• Paper pencil
• Apparatus

10
Activity 4 Using an Anemometer Underground

• Description
• Tell the team that they will be going underground
  to take readings with an anemometer.
• Emphasize the following in describing this
  activity
• Proper procedure in taking a reading
• Reporting the finding correctly, and
• Working under O2

11
Activity 4 Using an Anemometer Underground

• Description
• Have team members or the benchman prepare the
  apparatus. When ready, the team should get under
  O2.
• Have the captain take the team underground to a
  pre-arranged site to take air readings with an
  anemometer and to measure the cross-sectional
  area of the airway

12
Activity 4 Using an Anemometer Underground

• Description
• You should accompany the team. They can report
  their findings to you as though they were
  reporting to the command center.
• If you wish, go ahead and calculate the airflow
  in cubic feet per minute. The team will probably
  want to know a final figure.

Activity 4 Using an Anemometer Underground

• Evaluation
• Use the following checklist to aid you in
  evaluating the teams performance. Be sure to
  list and discuss any problems the team
  encountered.

Activity 5 Building Temporary Bulkheads Level
2

• Purpose The team will develop skill in building
  temporary bulkheads and will practice working
  together as a team while under O2.
• Type Underground work problem
• Materials
• Apparatus
• Other team equipment
• Construction materials for building a bulkhead
• Tools for building a bulkhead

16
Activity 5 Building Temporary Bulkheads Level
2

• Description
• Tell the team that their assignment is to build a
  bulkhead in a specified area.
• This activity can vary in difficulty depending on
  the teams experience and how challenging you want
  to make it.

17
Activity 5 Building Temporary Bulkheads Level
2

• Easier Assignment
• Construct a brattice bulkhead
• Materials provided at site
• Work at a slow pace
• Team told exactly where to build bulkhead
• Team should prepare site as necessary before
  putting up bulkhead.

• Harder Assignment
• Construct a brattice or a wood bulkhead
• Team must transport materials to a site nearby
• Work at a faster pace
• Team given general area, must pick exact site.
  (For instance, they should choose a spot with
  good back and even surfaces.)
• Team should prepare site as necessary before
  putting up bulkhead

18
Activity 5 Building Temporary Bulkheads Level
2

• Description
• Have team members or the benchman prepare the
  apparatus. When ready, the team should get under
  O2.
• Have the captain take the team underground to a
  pre-arranged site to take air readings with an
  anemometer and to measure the cross-sectional
  area of the airway

19
Activity 5 Building Temporary Bulkheads Level
2

• Description
• You should accompany the team. They can report
  their findings to you as though they were
  reporting to the command center.

Activity 6 Practicing Exploration Duties
Level 1

• Purpose Team members will practice coordinating
  their individual duties with the team objective
  of advancing and exploring a specified distance
  underground.
• Type Underground work problem

• Team equipment
• Gas detectors
• Map and Mapboard
• Communication equipment

• Fresh Air Base Equipment
• Map
• Communication equipment

24
Activity 6 Practicing Exploration Duties
Level 1

• Arrangements
• Arrange for the team to explore a small area of
  the mine with an easy terrain.
• Prepare copies of a map of the area to be
  explored.
• At the starting point of the exploration, set up
  a simple fresh air base with a map and
  communication equipment.

25
Activity 6 Practicing Exploration Duties
Level 1

• Arrangements
• Have someone (perhaps the team alternate) stay at
  the fresh air base to handle communications and
  to mark the map,.
• Also, have someone stay at the fresh air base to
  serve as the communications line, or cable
  attendant.

  single level mines tie-in all crosscuts and
  adjacent entries.)
• Tell the team they will be evaluated on how they
  function as a team and how they perform their
  individual duties (such as mapping, gas testing,
  ground testing, communications.)

  fresh air base, have the team members check their
  equipment and get under O2.

28
Activity 6 Practicing Exploration Duties
