353.080 Drilling through coal bed.
(1)
(2)
A well penetrating one (1) or more workable coal beds shall be drilled in such
manner as will, if practicable, exclude all oil, gas or gas pressure from the coal bed,
except such as is found in the coal bed itself. Each string of casing that is run
through a workable coal bed shall be seated at least thirty (30) feet below the coal
bed in twenty (20) feet of cement, mud, clay or other nonporous material that will
make an effective seal. If a second workable coal bed is found less than thirty (30)
feet below the first workable coal bed, the casing shall be seated and mudded off as
above provided at least thirty (30) feet below the second bed. If gas is found
between the two (2) beds, it shall be treated as prescribed by KRS 353.090. After
any such string of casing has been properly seated, drilling may proceed
immediately.
When a well is drilled through the horizon of a coal bed where the coal has been
removed, the hole shall be drilled at least thirty (30) feet below the coal bed, and
shall be of a size sufficient to permit the placing of a liner, which shall start not less
than twenty (20) feet beneath the horizon of the coal bed and extend not less than
twenty (20) feet above it. Within this liner, which may be welded to the casing to be
used, shall be centrally placed the largest size casing to be used in the well, and the
space between the liner and the casing shall be filled with cement as the liner and
casing are lowered into the hole. Cement shall be placed in the bottom of the hole to
a depth of twenty (20) feet to form a sealed seat for both liner and casing. Following
the setting of the liner, drilling may proceed. If it is necessary to drill through the
horizon of two (2) or more coal beds where the coal has been removed, the liner
shall be started not less than twenty (20) feet below the lowest horizon penetrated
and shall extend to a point not less than twenty (20) feet above the highest horizon
penetrated.
