A Review of the Federal Surface Coal Mine Blasting Regulations

On August 3, 1977 the 95th Congress passed Public Law 95-87, the Surface Mining Control and Reclamation Act of 1977. This Act created the Office of Surface Mining Reclamation and Enforcement (OSM), which was given the responsibility of formulating regulations to implement the Act. This paper explains the rationale behind the specific provisions of the final blasting regulations, which were published in volume 44, No. 50 of the Federal Register, dated March 13, 1979. The major items covered by the regulations include preblasting surveys, blasting schedules, protection of the public, ground vibration limits, the scaled distance equation, airblast limits, blasting procedures, and record keeping. The regulations are designed to protect the safety and well-being of the public and to protect buildings and structures such as wells, pipelines, and storage facilities from damage.
