                                 CODE OF VIRGINIA

 UNDERGROUND STORAGE OF EXPLOSIVES AND DETONATORS (§ 45.2-721)

A. If a supply of explosives or detonators for use in one or more sections is
stored underground, it shall be kept in a section box or magazine of substantial
construction with no metal exposed on the inside. Such box or magazine shall be
located at least 25 feet from any roadway or power wire and in a reasonably dry,
well rock-dusted location protected from falls of roof. In a pitching bed, where
it is not possible to comply with such location requirement, such box shall be
placed in a niche cut into the solid coal or rock.

B. If explosives and detonators are both stored in the section, they shall be
kept in separate boxes or magazines not less than 12 feet apart if feasible; if
kept in the same box or magazine, they shall be separated by a substantially
fastened hardwood partition at least four inches thick or the equivalent. Not
more than a 48-hour supply of explosives or detonators shall be stored
underground in such box or magazine.

C. If explosives and detonators are kept near the face for the use of miners,
they shall be kept in separate individual closed containers, in niches in the
ribs, not less than 12 feet apart, and at least 50 feet from the working place
and out of the line of blast. Each such container shall be constructed of
substantial material and maintained electrically nonconductive. Where it is
physically impracticable to comply with such distance requirements, the
explosives and detonator containers shall be stored in the safest available
places not less than 15 feet from any pipe, rail, conveyor, haulage road, or
power line, not less than 12 feet apart, and at least 50 feet from the working
face and out of the line of blast.

D. Explosives and detonators shall be kept in their containers pursuant to
subsection C until immediately before use at a working face.
