Classification 1704.

1704-02 Quarries, N.O.C.
Applies to establishments engaged in quarrying, not covered by another classification (N.O.C.), to extract large solid stone such as, but not limited to, limestone, sandstone, granite, marble, slate, hard shale rock, ballast rock, cement rock, coral rock, etc., from hillsides or open pits. Operations contemplated by this classification involve exposing stone with use of drag lines, power shovels, scrapers or other earth moving equipment. In some instances, blasting with explosives is performed on large stone masses to break portions loose. The stone is separated into large blocks, sometimes called loafs. There are several methods to cut a loaf - line drilling, wire sawing, diamond wire sawing or chiseling. The loafs are removed from the quarry pit and taken to the surface. This classification includes all other activities occurring on the surface of the quarry site which could involve the further cutting of the loafs or the crushing of stone into smaller pieces.
This classification excludes open pit mining operations which are to be reported separately in classification 1703, and underground mining which is to be reported separately in classification 1702.
