Official statutory text
In all shaft mines the openings to the surface hereinbefore
provided for shall be separated from each other by natural strata at
all points by a distance of not less than one hundred fifty (150)
feet, and at all mines worked by slope openings, the distance
separating openings shall not be less than fifty (50) feet of
natural strata: Provided, that in any mine opened heretofore the
