Sustainability assessment has received numerous attentions in the mining industry. Mining sustainability includes the environmental, economic, and social dimensions, and a sustainable development is achieved when all these dimensions improve in a balanced manner. Therefore, to measure the sustainability score of a mine, we require an approach that evaluates all these three dimensions of mining ...

the lead and zinc sample from goosh-e-fill mine with 2.4%pb, 8.0%zn and 10.0% fe, was used in different flotation experiments to recover lead and zinc minerals. the valuable minerals in prepared sample were oxidized and the results showed that the lead minerals floated at ph= 9.5 and 11.5, probably it can be due to existence of two or more types of lead minerals. the best result was achieved fo...

The purpose of this paper is to investigate the application of a combined finite-discrete element program, such as ELFEN, for the simulation and prediction of backfill stope failure risks due to blast loading effects in underground mines. A real size of a backfilled stope blasted in the nearby rock of the paste fill is modelled. The dynamic fracture propagation and fragmentation in rock and the...

Mavres Petres mine is an underground mine, located in Chalkidiki, northern Greece, that owned and operated by Hellas Gold; a wholly subsidiary of Eldorado Gold Corporation. The extracts highgrade lead zinc orebody using drift fill mining method. Backfill integral part cycle at mine. Filtered coarse tailings mixed with cement are used for making cemented hydraulic backfill surface batching plant...

Seabed-structure interactions are responsible for the burial of heavy objects, such as mines, pipelines, concrete breakwaters, platforms, debris, and other objects on the seafloor. In low shear strength muds, these objects are known to bury at impact or to sink into the sediment if the buoyant weight of the object exceeds the bearing capacity of the seafloor. In higher energy sandy sediments, b...

This article presents the use of Answer Set Programming (ASP) to mine sequential patterns. ASP is a high-level declarative logic programming paradigm for high level encoding combinatorial and optimization problem solving as well as knowledge representation and reasoning. Thus, ASP is a good candidate for implementing pattern mining with background knowledge, which has been a data mining issue f...

sarcheshmeh copper mine, with the final reserves of 828 million tons of sulfur ore and average grade of 0.74%, is known to be the largest open pit of iran and most probably the second largest copper mine in the world. this mine is located in the seismotectonic zone of central-iran, and 23 km away from the 150 km long rafsanjan active fault.in this study the vulnerability of the west wall of the...
