A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.

In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the ...

Surface mining is commonly used to extract coal and copper, and increasingly, precious metals like gold. Underground mining is used for gold, platinum, zinc, lead, and increasingly, coal. As can be seen, surface mining is much more advantageous than its counterpart.
Background & Burden. Slip, trip, and fall (STF) hazards in mining environments pose safety risks to mine workers. According to an analysis by NIOSH researchers of MSHA data, about 22% of all non-fatal injuries reported to the Mine Safety and Health Administration (MSHA) between 2014 and 2018 were associated with STF incidents.Each STF incident led to an average of 60 lost workdays.
Traditional surface mining has left untold tons of minerals underground, simply because there was no way to get to it safely and efficiently. The Vermeer innovative Terrain Leveler surface excavation machines can work where explosives can’t, with top-down cutting that lets you reach valuable mineral seams and get the most product out of the ground as possible.
Open-pit mining is an extremely effective surface mining technique for extracting minerals, coal and other useful materials that are covered by relatively thin overburden layers. However, it takes the right equipment to penetrate the surface rock and reach the underlying layer in a timely and efficient manner.
Apr 24, 2017 Blasting is an integral part of surface mining operations. To uncover coal reserves, the rocks overlying the coal are broken with explosives and excavated with various types of large earth-moving equipment. Without blasting, a vital part of the nation's energy reserve would be inaccessible.
