THE TOPCON MINING DIFFERENCE. We've been a part of surface and subsurface mining for decades, and we know what it takes to stay successful. What we've learned allows us to provide real solutions for the work you do.
Analysis of Energy Consumption in Surface Coal Mining. The coal mining industry consumes a significant amount of energy, primarily diesel fuel and electricity. The continuous global increase in energy demand, high energy prices and environmental issues related to carbon dioxide emission represent a substantial challenge for the mining industry.
Apr 25, 2017· Surface water isn't simply water sitting in a pond, lake or river. The Arizona Department of Water Resources classifies surface water as water from all sources, whether it .
Surface vs Underground Coal Mining March 01, 2010 The decision to develop a coal reserve using surface or underground mining is governed by a combination of several geologic, safety, economic, physical, regulatory and engineering considerations.
Subsurface geology is the study of the physical properties and location of rock and soil found below the ground surface. One of the most valuable reasons for learning about the subsurface is understanding the materials below manmade structures.
Dec 15, 2016· Match the mountains with the plates involved. A. Appalachians Two oceanic plates B. Andes One continental plate, one oceanic plate C. Aleutians Two continental plates D. .
Surface Ground Control Compaction Grouting. This can be performed when ground conditions are "soft" or incompetent. Polyurethane Grouts of an expansive type are particularly suitable for this purpose since they are injected in liquid form (allowing for excellent penetration) and during reaction are expansive, which simultaneously creates compaction and consolidation.
Sep 25, 2016· Surface mining, also called strip mining, delivers economically vital supplies of coal, which powers transportation and creates consumer products, boosting local economies. This type of mining occurs primarily on mountaintops, and dates back to the early 20th century when new machines made moving earth easier.

There are a couple types of Sub Surface mining. Underground Hard Rock mining deals with searching and mining for minerals such as zinc, nickel, lead copper and gold. Normally it is accessed using a vertical shaft that gives access to lower levels of the mine. After a shaft is installed then it will be possible to access the Ore or lode deposit.
Area strip mining is used in relatively flat areas. The overburden of soil and rock is removed from a large trench in order to expose the ore body. After the minerals are removed, the old trench is filled and a new trench is dug. This process is repeated until the available ore is exhausted.
Surface mining and deep underground mining are the two basic methods of mining. Surface mining accounts for around 80 percent of production in Australia, while in the US it is used for about 67 percent of production. Globally, about 40 percent of coal production involves surface mining.
Oct 20, 2015· Surface rights specifically refer to the ownership of the surface of the land. This includes dwellings, buildings, the right to till the land for crops and even the ability to dig into the land to bury underground storage tanks, such as wells or septic systems.
The Office of Surface Mining Reclamation and Enforcement (OSMRE) is a bureau within the United States Department of the Interior. OSMRE is responsible for establishing a nationwide program to protect society and the environment from the adverse effects of surface coal mining operations, under which OSMRE is charged with balancing the nation's need for continued domestic coal production with ...
On the basis of the type of mineral deposits, surface mining can be categorised as stratified and nonstratified. Stratified surface mining can be further subdivided into horizontal and inclined. Nonstratified is divided into vertical vein, and massive stockwork or pipe.
About Mining and Surface Certification (MASC) MASC was established in October 2008 and in this time obtained accreditation from the Department of Mineral Resources, SANAS and Department of Labour as well as International IECEx Accreditation. MASC has more than 50 years Ex experience amongst its technical specialists.
