METHOD OF OPEN

Sep 19, 1972The present invention relates to mining and, in particular, to a method of open-pit mining. In an open-pit mine which is used when the deposit of ore or minerals to be mined starts from or lies adjacent to the surface of the ground it is known to establish communications between the working site or the mining level in question and the surface by means of a transport track or ramp which

Wireless Mesh Network

A wireless mesh network is a multihop wireless network formed by a number of stationary wireless mesh routers. These routers are connected wirelessly using a mesh-like backbone structure. Some of the routers function as a wireless access point for clients (e.g., laptops and smart devices with wireless access) to attach themselves to the network.

Open Pit Mining 2012

Open pit mining is used to extract ore in rock bodies that are at or close to the surface of the Earth. Large‐scale equipment ‐drills, shovels, and trucks ‐are used to make operations efficient and economical. When they move in, the ore is dug up and sent to a mill for

Mining

Most iron ore mining operations use the 'open pit' method, where miners drill into the rock and blast the ore-bearing material loose with explosives. Huge excavators are then used to gather the loosened ore. To mine metallurgical coal, which will later be turned into coke, it's usually necessary to sink vertical mine shafts to access coal which is deposited in layers or 'seams

Basics of an open pit mine

Open pit mines can be used in coal mining, and they are used extensively in hard rock mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.

Shaft Mining and Open Pit Mining by Victoria Smith on

Shaft mines hold the record for being the deepest mines in the world. Although there are mine shafts all around the world, most shaft mines are located in South Africa because it has so many diamond and gold deposits. In 2003, the deepest mine was the East Rand mine at 3585 m,

Konkola Copper Mines warns part of Nchanga open

Jul 03, 2020The mine has marked out a 90-metre wide hazard exclusion zone in which the potential collapse is expected to occur. It is "at least" 60 metres away from nearby communities, he said. Apart from the Nchanga open pit, KCM also operates the Nchanga and Konkola underground mines, concentrators, a smelter, a tailings leach plant, and a refinery.

A comparative study of truck cycle time prediction methods

Sep 07, 2010– The purpose of this paper is to compare the predictive capability of three methods of truck cycle time estimation in open‐pit mining: computer simulation, artificial neural networks (NNs), and multiple regressions (MRs). The aim is to determine the best method. The most common method currently used is computer simulation., – Truck cycle times at a large open pit mine are estimated

Safety in Open Pit Mining

Incidents with moving mining equipment are often triggered by a lack of adequate visibility, insufficient job site communication, and operator's fatigue. Therefore, clear rules for traffic management and job site communication are required. Such systems are common practice within Australia open pit mines. In surface mining, draperies are

How Wireless Mesh Networks Work

Mesh nodes are small radio transmitters that function in the same way as a wireless router. Nodes use the common WiFi standards known as 802.11a, b and g to communicate wirelessly with users, and, more importantly, with each other.. Nodes are programmed with software that tells them how to interact within the larger network.
