SMCRA also created the Office of Surface Mining, an agency within the Department of the Interior, to promulgate regulations, to fund state regulatory and reclamation efforts, and to ensure consistency among state regulatory ...
Surface mining and deep underground mining are the two basic methods of mining. The choice of mining method depends primarily on depth, density, overburden, and thickness of the coal seam; seams relatively close to the surface, at depths less than approximately 55 m (180 ft), are usually surface mined.

Blast mines are buried close to the surface and triggered by pressure. A weight between 4 and 24 pounds (1.8 and 10.9 kg), the weight of a small child, is usually enough to set one off. They are usually cylindrical with a diameter of 2–4 inches (5.1–10.2 cm) and a height of 1.3–3.0 inches (3.3–7.6 cm).
