iving one or more good
seasoned wooden plugs, or a lead plug, as the case may require, so
that no gas or oil may escape, or any water or destructive matter
force itself into the oil or gas sand, or rock formation. Upon such
seasoned wooden plug or plugging material shall be filled at least
thirty feet of cement properly mixed with sand, or thirty feet of
good clay or rock sediment properly prepared.

If any well has passed through a workable vein or seam of coal, it
shall when it is abandoned be plugged in the following manner: A
seasoned wooden plug shall be driven to a point thirty feet below
the lowest workable seam of coal and the hole filled with cement to
a point at least twenty feet above this seam of coal, at which point
another wooden plug shall be placed and the hole filled for a
distance of twenty feet with cement or properly prepared clay, or
rock sediment. If there is more than one seam of coal the next seam
above must be plugged off in like manner.

=When well penetrates the excavations of any mine.=

In the event that a well being drilled penetrates the excavations of
any mine, it must be cased with casing of approximately the same
diameter as the diameter of the hole, the hole to be drilled thirty
feet or to solid slate or rock and not less than ten feet below the
floor of such mine, and the casing shall be placed in the following
manner: One string of casing shall be placed at a point above the
roof of said mine so as to shut off all of the surface water; then
the hole drilled through said mine and another string of casing put
in. The bottom of the second string of casing, or the one passing
through said mine, shall not be nearer than ten feet, or more than
thirty feet from the floor of the mine where it passes through the
same.

When any well which has been drilled is to be abandoned and has
passed through the excavations of any coal mine from which the
minable coal has not all been removed, the person, firm or
corporation owning said well shall leave in said well the casing
passing through said mine from a point not less than ten feet, nor
more than thirty feet below the floor of said mine, and extending
above the roof of said mine at least five feet. A seasoned wooden
plug shall be driven to a point at least forty feet below the floor
of the mine and the hole above said plug together with the casing
left in, which extends through the coal, shall be filled with
cement; then a seasoned wooden p
