Examine more frequently after rain, freezing and thawing. Scale highwalls to eliminate hazards, e.g. loose rocks or overhangs. Perform scaling from a position that will not expose miners to injury. Until hazards are corrected, …
Highwall miners link underground and surface mining operations by extracting coal from exposed horizontal seams in open-pit mines. This is done via a mobile system that contains a continuous miner controlled from the operator's cabin, a retractable conveyance system, and a vertical conveyor that handles and stacks the coal for transport.. The point at …
Multiple seam highwall mining When thick seams exceed the working height of the highwall mining equipment or a thick seam splits into thinner seams, multiple seam mining approach can be considered (Ross et al., 1999; Zipf and Mark 2005). The ideal situation in multiple seam highwall mining is to accurately stack upper and lower seam …
Figure 9 shows the damaged highwall mining equipment by the falling rocks from the . top soil and weathered rock zone. Apparently, the highwall under the failed top zone has failed .
However, new highwall mining equipment is massive and can cost upwards of $2 million, usually more. Such an expenditure would adversely affect other business expansion priorities and overall cash flows. A decision to rebuild miners instead of buying equipment would be more economical. Securing the financing needed to reconstruct the miners was ...

Highwall Mining. Moura's highwall mining system was commissioned in mid-1997, BHP has estimated that by 2012 there would be 127Mt of highwall reserves at the mine. Since over 80% are held in seams that dip steeper than 6°, conventional highwall mining equipment cannot operate satisfactorily.

Overview. Linking underground and surface mining operations, the ® highwall mining system is a testament to versatile mining equipment. It offers a safe and innovative method for extracting coal from outcropping seams in a multitude of applications.
Highwall mining is when machines collect minerals from unmined walls with overburden and exposed ores. It is a combination of surface and sub-surface mining. ... Surface mining uses a diverse array of equipment. Mining is dangerous in its own right, but using the wrong equipment increases your chances of getting hurt.
Highwall Mining Evolves. From the bridge of the highwall miner, an operator advances a cutterhead, or an unmanned cutter module, into an exposed coal seam. The machine rests on crawler tracks on the bench below the highwall. Coal is extracted in parallel rectangular (the width of the cutterhead) entries spaced at various …
Highwall Safety. Highwall stability is essential for open-cut mining. In these particular projects, otherwise known as open-pit mining, employs a technique in which rock and minerals are extracted from a borrow pit, or sandbox. For long-term highwall performance, the substance properties that makeup mining sites—or more specifically, the ...
Even highwall mining operation is proved to be a safer mining technique, though there is threat of collapsing of roof of entry, web and barrier pillars (Porathur et al., 2017). The biggest threat in a highwall mining operation to both equipment and personnel's safety is ground control (Shen, 2014).
Highwall mining is a proven technology in USA and Australia to extract the blocked coal in thin non-workable seams and the coal blocked in the highwall of opencast mines. In USA, highwall mining contributes about 4.0 % share of total coal production. In India, the highwall mining is in the nascent stage. So far only two highwall mining are ...
7.3.4: Highwall Mining. Highwall mining is very similar to auger mining in its concept, where the entry into the coal seam in made at the highwall of the ultimate pit limit. The difference lies in the use of a more …

The highwall mining equipment . dictates the hole width which varies from 2.7 to 3.6 . m. In-situ vertical stress depends on the overlying . rock density and overburden depth. Vertical stress
Highwall mining is a method that involves using a continuous highwall miner system (CHM) to extract coal from the remaining coal seams, which has proven to be an effective and safe method for extracting coal after open-pit mining. However, application cases globally have shown that the feasibility of highwall mining in open-pit coal mines …
The mining machinery is operated remotely from an operator's cab that is located on the surface. The tunnel is mined the maximum distance allowed by equipment design and geological conditions. At that point, the equipment retracts from the hole and moves down the highwall and drives another entry parallel to the one it just mined.
The capacity of the Superior Highwall Miner, a company owned by Corp, being acquired is broadly in line with the highwall miner operated by MHW. The purchase price of the second highwall miner and related equipment is $2.5 million with $100,000 being payable on signing of the agreement and the balance to be paid within …
The primary methods of surface coal mining used in Pennsylvania are: Strip Mining: Layers of soil and rock overburden are removed the coal exposed coal seam is excavated. The area is then backfilled, regraded, and replanted during the reclamation process. Highwall Mining: An outcrop of coal is removed by traditional excavators, or by using ...
