(pdf) surface mining methods and equipment Surface mining is generally considered to provide better recovery, grade control, flexibility, safety, and working environments than underground mining. Figure 3 shows a comparison of the total injury rates in US coal mines. Coal mining Choosing a mining method Britannica
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 openpit, stripping, dredging and mountaintop removal.
Zhengao et al. and Mishra et al. distinguished a narrower purpose of the lateral mining method, for lowdipping strata of high thickness. [13,14] In turn, for the surface mining of inclined and ...
When it comes to surface mining equipment, no one has more experience helping miners match the right product to a specific need than . Ranging from dozers, drills and draglines to trucks, shovels, loaders and a host of support equipment, our lineup isn''t just the industry''s broadest.
It is an advantageous mining method f or shallow orebodies – as a means of preventing surface subsidence. Historic, ultrashallow under ground coal mines (< 30 m) nevertheless are
These surface mining methods are considered to be more efficient and economical in extracting minerals as compared to most methods of underground mining. In fact, it can extract almost 90% of ore from a deposit. For this reason, surface mining is the most widely used method in North America.

mining equipments selection. This system is able to involve the expert knowledge in primary and secondary selection of equipment for surface coal mines [3]. In 1990, another expert system, in order to classify equipment, was planned in the open pit coal mine of Britain with the help of fuzzy logic.
Openpit and area mines are associated with extraction of thick deposits. These justify mining of deeper overburden/cover rock. They are typically multiple bench type operations with special consideration required for the vertical lift requirement...
Mar 09, 2018· Selecting a Mining Method. ... is a variation of roomandpillar mining in which the footwall of an inclined ore body is adapted for use of trackless equipment. ... Open pit mining method works best when the deposit is close to the surface as it is way more economical to use this method instead of underground mining. Open pit mining operations ...
In all methods of surface mining, first, the overburden is stripped off using, bucketwheel excavators remove the ore, which is loaded into haul trucks with shovel loaders. When the deposit is exhausted, the overburden is refilled in the crater, and the land is restored with the local vegetation.

Haul trucks and other large surface mining vehicles are capable of destroying smaller vehicles that cannot be seen by the operator. Traffic controls, training, and avoiding distractions are key to enhancing safety. Collision warning and avoidance systems can also help. Key Safety Practices Communicate and verify with all equipment operators any planned movements and location
