Time studies of mining operations

Abstract

The U.S. Bureau of Mines facility at Anvil Points, near Rifle, Colorado, was reactivated starting in May 1964 and was operated during 1965, 1966, and 1967. A research and development program was conducted to investigate the technical feasibility of room-and-pillar mining with explosives, crushing and Gas-Combustion Retorting techniques for oil shale. Mobil Oil Corporation acted as Project Manager for the cooperative industry group at Rifle which included Continental Oil Company, Humble Oil and Refining Company, Pan American Petroleum Corporation, Phillips Petroleum Company, and Sinclair Research, Inc. as Participating Parties. Costs of the Rifle operation were shared equally by the six participants. Each Participating Party was represented by personnel on the technical staff. The Colorado School of Mines Research Foundation, Inc. acted as lessor-of-record and supplied nontechnical personnel for administrative and logistic support. These Technical Memoranda have been prepared to provide rapid, on-the-spot reporting of research currently in progress at Anvil Points.
