The underground mining methods we use include room and pillar, narrow vein stoping and largescale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them .
Underground Mining: Stoping Methods. October 2016 by Chris Ralph. In an old mine that does not have stopes, you know the old miners did not take much if any ore out of that excavation. On the other hand, if you see large stopes within the mine you know that it is these places where the miners found profitable ore deposits within the vein.
A method of shorthole mining, cutandfill mining is used in irregular or steeply dipping ore zones, especially where the hanging wall limits the use of longheld methods. The ore is mined either in slightly inclined or horizontal slices then it is filled with sand, waste rock, or tailings.
Jul 21, 2016· Underground mining is the process of extracting minerals and ores that are located too far underground to be mined efficiently using surface mining methods. The primary objective of underground mining is to extract ore safely and economically while minimizing handling of waste rock. Typically, underground mine has less environmental impact.
Shortwall Mining. This method of mining was developed in the late 1960's to take advantage of the then recent development of suitable hydraulic longwall supports, coupled with the productivity and low capital cost of continuous miners and shuttle cars.
In this study, a computer program (UMMS) based on the AHP and the Yager's method was developed to analyze the underground mining method selection problems and produce the best underground mining method swiftly for different deposit shapes and ore bodies.
Aug 22, 2009· The advantages of surface mining are: * It is cheaper to extract the ore or metal than underground mining * Less chance of workers dying from toxic fumes, therefore it is safer unlike underground mining.
Underground Mining Underground mines in the United States are typically operated using one of two different methods: room and pillar mining or longwall mining. In room and pillar mining, rooms are cut into the coal bed leaving a series of pillars, or columns of .
Jeff has 30 years of mining and engineering experience specializing in surface and underground mining, construction, and energyrelated services, including production. With his extensive understanding of surface and underground mining, waste disposal, mine infrastructure, and mine economics, Jeff is able to coordinate these efforts in a way that maximizes the value of a Feasibility Study.
Underground mining method selection is one of the most important decisions that mining engineers have to make. Choosing a suitable underground mining method to extract a mineral deposit is very important in terms of economics, safety and productivity of mining operations.

Webinar Overview. This webinar will provide an overview of Cave Mining methods and the factors influencing the selection of the appropriate one for any given orebody. There will be discussion on the risks and advantages of the methods and the direction that the (hard rock) industry is heading. Participants will gain an understanding...
The four methods are: chamber and pillar mining, sublevel stoping with spent shale backfill, sublevel stoping with full subsidence, and block caving using load haul dump (LHD). All more » mine designs were developed for 85,000 tons per day minimum production or enough feedstock for 50,000 barrel per day surface processing plant.
Underground mining is carried out when the rocks, minerals, or precious stones are located at a distance far beneath the ground to be extracted with surface mining. To facilitate the minerals to be taken out of the mine, the miners construct underground rooms to work in.
Dry rock fill: Dry rock fill is rock waste, surface sands, gravels, or dried tailings. The fill is either dropped down a raise, or tipped into an open stope by a Load Haul Dump (LHD) or dump trucks. Dry rock fill is most suited for the cut and fill mining method.
Underground Mine Design, Planning and Engineering. We have years of firsthand underground mine engineering and operating experience in most countries and across multiple commodities using all common mining methods. As a global SRK group, we have specialist underground mining expertise to provide solutions for the unique features of each project.
