1. Sub-Sector Description
Sub-Sector # 1 : Exploration
/. Seismic Geophysical/Mineral Exploration(Industry # 0 9200)
This industry involves conducting exploration using seismic technology for the purpose of
locating formations beneath the earth’s surface that may produce usable minerals such as coal, or
oil and gas.
The basic procedure used to locate favourable formation beneath the earth’s surface is to send
shock waves into the ground, and record the patterns on seismic recording equipment.
When exploring for oil and gas, any one of the following three methods may be employed to
create the shock waves:
1 . Seismographic - D ynamite exploded in a s hot hole;
2. Vibraseismic - t ractor or truck mounted vibrators which are released to the ground at certain
points; and
3. Vacuum Guns - t ruck mounted piston strikes base plate to send shock waves through the
ground
When exploring for minerals, such as coal, shock waves are created by means of small hand
tools. Larger equipment is not required as minerals formations are generally not located as deep
below the surface as are oil and gas.
Sound waves are received through instrument referred to as geophones. The geophones are in
turn wired to recording instruments that log the sound wave patterns. The data processing and
analysis of the obtained information, may or may not, be part of the contract.
This industry does not cover shot hole drilling. This is normally subcontracted out to another
company classified in industry 09201. Should an employer conduct drilling in conjunction with
exploration, an additional industry is required.
Geophysical Exploration, other than seismic, is classified in industry 86405. The key difference
is the generation and recording shock waves.
iu Shot Hole Drilling (Industry # 0 9201)
The purpose of this industry is to drill bore holes for the purpose of holding explosives used in
seismic exploration activities.
Shot hole drilling is p erformed with a s mall truck-mounted driller. This is normally a s hallow
drilling operation, drilling to a d epth of 50 to 75 ft. This activity involves drilling only, as an
exploration crew is responsible for placing and discharging the explosives. When the explosives
are discharged or shot, the vibrations are recorded on a s eismograph.
This industry applies specifically to shot hole drilling. Water well drilling is p erformed in a
similar manner but is included under industry 42130.
