Whatever your business is handling from coal to copper ore, from iron ore to overburden to be successful in the fields of openpit mining you need a strong partner. We offer you over 50 years of experience in delivering electrical and automation equipment for openpit mining and highvolume bulk material handling.
ADVERTISEMENTS: List of equipment used in opencast coal mining are: 1. Bulldozer 2. Craper 3. Ripper 4. Tractor Shovel 5. Dipper Shovel 6. Stripper Shovel 7. Pull Shovel or Hoe 8. Dumpers or Tippers 9. Drag Line 10. Road Grader 11. Rock Drills. Opencast mining is the oldest method of excavating minerals but the mining []
According to the Bureau of Labor Statistics, the mining industry consists of five major segments: coal mining, gas and oil extracting, metal ore mining, nonmetal mineral mining and supporting activities such as resource transportation.
(40% equipment effectiveness against %). This factor is expected to fuel the innovations and production in mining equipment for open pit mining. Furthermore, the development of highperformance equipment, with increased automation, has made extraction of ores without declining the grades comparatively cheaper, in turn, propelling the growth
Openpit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of openpit mining. The removal of this material is known as stripping. The strippingpit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit
Open pit mining also called open cut mining or open cast mining is a surface mining technique used to extract rocks and minerals. It requires largescale equipment, including shovels and drills. Motor graders also play a role, maintaining haulage roads so that both equipment and mined material can be transported to and from the mines.
In general, underground mining is more expensive than open pit mining as with open pit mining the minerals are found near the surface at a maximum of approximately 200400 meters depth in bulk tonnage.. The mining costs are estimated in a mining companys feasibility study which, when available, can be found on the companys website (often hidden between the news releases).

Openpit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. Openpit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels.
