The mining industry pre-dates sophisticated simulation software and the computers it runs on by thousands of years. Recently, we sponsored a webinar together with NASA Tech Briefs on “Mining and Hydrogeology: Porous Media Flow Simulations with COMSOL”, featuring environmental consultants Jorge Molinero and Elena Abarca from AMPHOS 21.

In this conference we have brought together a community that is scientifically diverse in an event that allows for inspiring contacts about the use of COMSOL Multiphysics. It is an event to connect with the Spanish and Portuguese COMSOL Multiphysics users and participate in training opportunities and events explicitly designed for the academic and engineering community.
Oral and poster presentations highlight achievements in multiphysics modelling and simulations using COMSOL.

Some of the present metallic ores mines are located in areas formed by a heterogeneous fractured massif where groundwater flows preferentially through fractures.
Underground mining in these zones can cause impacts in streams, lakes and change the natural water balance of the watersheds, leading to conflicts between traditional uses of water and the mining activity.

Most of mining works, either on the surface or in the underground, demand continuous groundwater pumping in order to operate under dry conditions. When the mining activity stops, dewatering also stops and mining facilities begin to flood, quite quickly at the beginning but becoming slower as the water level in the pit lake rises.

The block caving mine is considered by the mining industry as one of the natural replacements of the current open cut mines in the near future. Mudrush is a sudden inflow of a sort mud ore into underground mining facilities. It may cause harm to people and equipment, production delays, dilution and mine closure.
The purpose of this numerical investigation is to obtain a more complete understanding about the permeability in fragmented materials and its applications to underground mining using COMSOL Multiphysics® software.

The performance of the oil reservoir is decisively determined by the hydraulic permeability of the rock and the possible flow paths. During the production phase, the petrophysical properties of the rock may deteriorate due to highly viscous oil deposits, especially in the near of the borehole. Therefore, it is a challenge to restore the permeability in this area.

In underground mining operations, the mined-out spaces (called stopes) need to be backfilled to maintain the stability of surrounding rock mass and increase the ore recovery. Cemented paste backfill (CPB), a mixture of water, binder, and tailings, has been intensively utilized in underground mining operations to fill the stopes. After preparation, the fresh CPB is transported into stopes via gravity and/or pipelines.

Enhanced oil recovery (EOR) is expanding worldwide to produce more oil from the existing reservoirs to fulfil the demand of the global consumption, which increases on yearly basis. Thermal methods like steam injection and its variations are the most famous methods applied in heavy oil reservoirs and bitumen to produce as much as possible oil. Understanding heat distribution during this process is the keystone to optimize the process and reduce the cost of oil barrel.

A three-dimensional multiphase laboratory experiment was simulated with a view to evaluating the subsurface distribution of non-aqueous phase liquids (NAPL). The experiment was set-up to reconstruct the migration of hydrocarbon-leaks, occurring in the earth´s surface, predominantly driven by capillarity. Likely real-life occurrences and typical subsurface sources may include but not limited to, buried pipelines and underground storage tanks, from where leakages discharge.

Time-lapse electrical resistivity tomography (ERT) method provides a non-invasive way to monitor subtle sub-surface changes caused by water flow such as in an infiltration test. Problems arise when the inversion models contain artifacts due to measurement errors, rapid change in soil electrical property during measurement time, etc. A new approach was developed by Kim et al. (2004) and (2009) that incorporates the time constraint in the ERT inversion scheme that simultaneously inverts the entire monitoring data set.

When carbide particles such as titanium carbide particles are mixed into the metal powder, the process results in highly wear resistant metal matrix composite (MMC) coatings, which are commonly applied in several heavy duty applications, for example on mining tools. As the carbide particles are often different in density compared to the metal matrix material, they tend to accumulate on the melt pool surface or on the bottom, respectively.

A 3-D COMSOL model was established to investigate the heat and mass transfer in a hollow fiber membrane (HFM) module for direct contact membrane distillation (DCMD).
Membrane distillation is a separation process that relies on vapor pressure gradients to drive the production of purified water across a hydrophobic membrane. In direct contact membrane distillation, both the hot water and cold permeate are in direct contact with the membrane.

Geothermally driven natural convection in enclosures is a ubiquitous process occurring in many physical environments such as caves, mines, etc. We have numerically simulated laminar and turbulent natural convection in isolated air-filled cavities, buried in a more conductive rock mass. We have modeled heat transfer using COMSOL's Convection and Conduction mode.
