Pennsylvania Mining Statutes Annotated
From Author's Explanation: "This bulletin is intended to include every legislative enactment of the Commonwealth of Pennsylvania relating to the mining and mineral industries. The entire body of mining laws is set out for these obvious reasons: (1) To show the progress and advancement made, and the changes through which the enactments have passed; (2) an author may not assume the determination of what particular laws are in fact in effect, as this is within the jurisdiction of the courts alone; (3) it was at least necessary to set out all acts that had at any time been construed by the courts."
