A dedicated publication, the Maine Mining Journal was published starting in 1880. Although the boom was partially an economic bubble, some mines such as the Douglass Copper Mine in Blue Hill produced viable quantities of copper and continued to do so until 1918 under the control of the American Smelting and Mining Company.
A variety of surface mining methods has been developed, including strip mining, auger, area strip, open pit, dredging, and hydraulic. Sound planning and design techniques are essential to implement alternatives to meet the myriad of laws, regulations, and mining and visual resource objectives.

This study focuses on toughness enhancement of basalt fibre-reinforced shotcrete (BFRS). Four-point bending experiments of underground shooting and curing beams combined with a roadway-supporting deformation monitoring test were conducted. The flexural performance was analysed based on the toughness standards, namely, DBV-1998, JSCE SF-4, and nuclear magnetic resonance (NMR) pore .
conveyor or hydraulic transport in mines. The most common transportation method in surface mining is classic truck and shovel combination. This operation almost consists about 50 to 60% of total operating costs in surface mining. It is necessary to use shovel truck combination efficiently for improving economy in the mining sector.

SURFACE MINE BLASTING Proceedings: Bureau of Mines Technology Transfer Seminar, Chicago, IL, April 15, 1987 Compiled by Staff, Bureau of Mines ABSTRACT The Bureau of Mines has sponsored a comprehensive research program to enhance the safe, effective, and efficient use of blasting technology by the mining industry.
In surface mining operations, ultra-heavy trucks operate on haul road networks which are typically from 10�40 km in length. These road networks are often not optimally designed and maintained and as a result, identifying and remediating road functional defects is problematic. Most surface mine operators agree good roads are desirable, but find it difficult to translate this into an ...
BENCHMARKING THE ENERGY CONSUMPTION OF CANADIAN OPEN-PIT MINES 2 METHODOLOGY The total energy costs for open-pit mining operations for the nine operations were compared. These energy costs were, in turn, subdivided into two components: $/kWhe and kWhe/kilotonne of ore mined.
The main advantage of the new stemming method is the reduction in the cost of blasting. At a basalt quarry, blasting costs per unit volume of rock were reduced to 15% by increasing burden and spacing distances. In addition, better fragmentation was obtained by using the plaster stemming method.
The Surface Mine Reclamation Program (SMRP) is part of the Washington Geological Survey within the Washington Department of Natural Resources. The program was created in 1971 after the legislature created the Surface Mining Act. The SMRP makes sure that all lands and waters within the state are protected and reclaimed after mining is complete.
