WAC 296-17A-0103   Classification 0103.  


0103-09 Drilling or blasting: N.O.C.

     Applies to contractors engaged in drilling operations for others not covered by another classification (N.O.C.). Work contemplated by this classification includes, but is not limited to, well drilling for oil, gas or water; exploratory well drilling; and drilling of holes in rock for shot holes. Such drilling generally contemplates the digging of a hole using a rotating or pounding type tool. Equipment used by drilling contractors includes earth auger drills, jackhammers, drilling rigs, and bits which will vary in size depending upon the terrain or material to be drilled and the depth and size of holes to be drilled. This classification also includes blasting operations not covered by another classification (such as the blasting of rock in connection with highway, street or road construction).

     This classification excludes drilling operations performed in connection with concrete or building construction which is to be reported separately in the construction classification applicable for the work being performed; drilling done in connection with all types of underground or surface mining and quarry operations which is to be reported separately in the applicable mining classification; and blasting performed as part of building demolition which is to be reported separately in classification 0518.


0103-10 Geophysical exploration: Seismic detection of the mechanical properties of the earth

     Applies to establishments engaged in geophysical exploration, by seismic detection, of the earth's subsurface. Work contemplated by this classification involves a seismograph work crew consisting of a party chief, a permit person, a surveyor, drillers, shooters, observers and a computer analyst. The seismic method utilizes a dynamite blast that simulates a miniature earthquake. The recorder of the vibrations is the sensitive earthquake detector which records the intense vibrations on a rapidly moving tape. The data collected from the tapes and photographic records are interpreted and a contour map of the rocks and their foundation to depths of several thousand feet is developed.

     This classification excludes geophysical exploration without seismic detection which is to be reported separately in classification 1007.
