§22-6-20. Same -- When well is drilled through horizon of coal bed from which coal has been removed.

When a well is drilled through the horizon of a coal bed from which the coal has been removed, the hole shall be drilled at least thirty feet below the coal bed, of a size sufficient to permit the placing of a liner which shall start not less than twenty feet beneath the horizon of the coal bed and extend not less than twenty feet above it. Within this liner, which may be welded to the casing to be used, shall be centrally placed the largest sized casing to be used in the well, and the space between the liner and casing shall be filled with cement as they are lowered into the hole. Cement shall be placed in the bottom of the hole to a depth of twenty feet to form a sealed seat for both liner and casing. Following the setting of the liner, drilling shall proceed in the manner provided above. Should it be found necessary to drill through the horizon of two or more workable coal beds from which the coal has been removed, such liner shall be started not less than twenty feet below the lowest such horizon penetrated and shall extend to a point not less than twenty feet above the highest such horizon.
