Abstract:

The general characteristics of gold deposits are reviewed, and a classification of gold deposits based on mineability is proposed. Evaluation, mlnlng and beneficiation methods are briefly discussed. It is concluded that the most viable targets for small-scale companies comprise deposits that require the least pre-production time and expense. Great potential exists for the small-scale reclamation of gold from tailings dumps and abandoned mines in Southern Africa. There is also potential for developing new smallscale gold mines in the Archaean greenstone terranes of the Zimbabwean and Kaapvaal c

Canadian hard rock mine extraction practices have commonly created shallow stopes, 12% of which have caved to surface, from instabilities originating from stope hangingwalls, crowns or footwalls.

The preference has been to use personal mining experience.<br>Several common rock mass environments are surveyed as well as the various ways in which shallow stopes have failed.

Abstract:

Energy conservation is an important policy for every nation. Exploiting sustainable energy resources has gained ground due to shortages and increasing prices of fossil fuels. Mining represents a significant portion of Canada's resource-based industry sector and consumes a huge amount of energy for operation and post-mining activities. Therefore, any cut in energy consumption lowers costs and increases profits. Underground mines have excellent potential for implementation of geothermal energy systems using one of two methods. In the first, underground mine water that has flowed through warm lay

Targeting marine diamondiferous deposits along the south-western Namibian coastline has involved the construction of seawall berms to advance the coastline and permit mining in previously subtidal areas. Large areas are mined out to bedrock level by the removal of overburden (sand and gravel), and after mining is complete, areas behind the seawalls fill with seawater, creating a series of coastal marine ponds that have the potential to function as saline wetlands corresponding to closed estuaries.

Abstract:

Spatial clustering of seismic events in mines has been widely reported in literature. Despite obvious visual correlations between spatial clusters of seismic events and geomechanical structures in mines (such as pillars, dykes and faults), very limited research has been undertaken to utilise this information to filter seismic data. A linkage between spatial seismic event clusters and discrete rockmass failure mechanisms is tenuous and not well established using current seismic analysis techniques. A seismic event clustering methodology is proposed. The first component of the methodology uses a

Comprehensive and reliable seismic analysis techniques can aid in achieving successful inference of rockmass behaviour in different stages of the caving process.

A seismic monitoring database was collected during cave progression and breaking into an open pit 550 m above the first caving lift. Five seismic analyses were used for interpreting the seismic events. Interpretation of the seismic data identifies the main effects of the geological features on the rockmass behaviour and the cave evolution. Th

Abstract:

A graph theory oriented algorithm for optimal ultimate pit limit design is developed. Mathematical proofs of optimality and convergence are given. The algorithm works on a 3-D block mine model and formulates the model into a directed graph consisting many trees. The vertices in the graph are identified with the blocks in the model and the imposed arcs in the graph represent pit slope constraints. The formation of each directed tree is based more on the ore-waste support concept than geometric constraints alone. The algorithm efficiently handles the joint support and re-allocation problems.

The adverse impacts that the conventional mining system results are ground vibration, noise pollution, air pollution, land degradation, ecological disturbances etc. This generates necessity of additional machineries and manpower, eventually cost of mining coal rises. And also due to existence of villages adjacent the mines, bl

Abstract:

Draglines have been explicitly used in coal mining for a no. of decades, either as stripper or stripper and coal extractor. As this equipment retains certain intrinsic benefits, which their rivals don’t have, they should essentially be operated in round-the-clock fashion for high productivity and low expenditures. In India, the advancement of giant surface mining projects like Bina and Jayant with setting up of high coal production targets (upto 10 MT/year) demands for systems to remove huge volume of overburden in minimum possible time. This has led to major changes in overburden/interburden

Abstract:

In mining industry, the challenging task of a mining professional comprises of the extraction of maximum natural resources with utmost safety of the miners. ¡§Blasting Gallery¡¨ method is a unique technique of depillaring thick seams for higher recovery of coal. The present study has been aimed to examine thoroughly BG method operational systems in Indian geo-mining conditions such as: „« Study of roof convergence with respect to face advancement during different stages of extraction of coal in Blasting Gallery panels in SCCL mines. „« Simulation of field conditions in the numerical model gene
