Design of Surface Mine Haulage Roads – A Manual By Walter W Kaufman and James C Ault ABSTRACT This Bureau of Mines manual for design of surface mine haulage roads covers such aspects of haulage road design as road alignment (both vertical and horizontal) construction materials cross slope and drainage provisions Each segment requires the use of specific equipment but there are several types of mining equipment that are used throughout the industry This equipment includes excavators draglines drills roof bolters continuous miners longwall miners rock dusters shuttle cars and scoops

Equipment selection

The equipment selection process for an underground mine design plan has an extremely wide scope as there are a myriad of parameters to consider when incorporating mobile and stationary equipment in hard or soft rock mining applications This article primarily focuses on the initial selection of mobile equipment in hard rock mining operations

Mining techniques can be divided into two common excavation types: surface mining and sub-surface (underground) mining Today surface mining is much more common and produces for example 85% of minerals (excluding petroleum and natural gas) in the United States including 98% of metallic ores

New to Mining? Here are the Most Common

The most common types of mining equipment vary depending whether the work is being carried out above or below ground or mining for gold metals coal or crude oil From drilling machines to excavators crushing and grinding equipment – the mining

Mining - Mining - Underground mining: When any ore body lies a considerable distance below the surface the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive and underground techniques must be considered Counting against underground mining are the costs which for each ton of material mined are much

ESTIMATION OF CAPITAL COSTS FOR ESTABLISHING COAL MINES IN SOUTH AFRICA Moshe Mohutsiwa A research report submitted to the Faculty of Engineering and the Built Environment University of the Witwatersrand in partial fulfilment of the requirements for the degree of Master of Science in Engineering Johannesburg 2015 ii DECLARATION I declare

When coal seams are near the surface it may be economical to extract the coal using open cut (also referred to as open cast open pit mountaintop removal or strip) mining methods Opencast coal mining recovers a greater proportion of the coal deposit than underground methods as more of the coal seams in the strata may be exploited This equipment can include the following:

Mining health safety

The mining industry has a reputation for being a risky business with health risks that are varied and often quite serious and it is important for miners to protect themselves accordingly Nevertheless mining doesn't have to be unsafe With the introduction of strict safety legislation and protocol as well as advances in safety equipment the industry has seen its fatality rate

Open-pit mining causes changes to vegetation soil and bedrock which ultimately contributes to changes in surface hydrology groundwater levels and flow paths Additionally open-pit produces harmful pollutants depending on the type of mineral being mined and the type of mining process being used

ANFO has found wide use in coal mining quarrying metal mining and civil construction in undemanding applications where the advantages of ANFO's low cost and ease of use matter more than the benefits offered by conventional industrial explosives such as water resistance high detonation velocity and performance in small diameters It is

Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals usually those containing metals such as ore containing gold silver iron copper zinc nickel tin and lead but also involves using the same techniques for excavating ores of gems such as diamonds or rubies
