Closure options under consideration at some iron ore mine sites in Western Australia include backfilling with mineralised and/or non-mineralised waste rock. Post-closure, following groundwater rebound, flow-through conditions may develop in the backfill located within the saturated zone below Read more... about Weathered Sulfidic Waste – Laboratory-Scale Tests for Assessing Water Quality in Backfilled Pits

With the variability of commodity prices and the constant increase of mining costs, it has become increasingly important to optimize pit slopes of mines, taking into consideration the complexity and the uncertainties presented by ground conditions. The variables in slope stability,

Groundwater inflow to open-pit and underground mines creates significant impacts both on mine operations and on the environment. Issues that commonly need to be addressed at different stages of engineering or environmental/ permitting studies include: (a) Engineering and economic risks Read more... about Use of Numerical Groundwater Modelling for Mine Dewatering Assessment

Water is a key component in the development of the mining industry; from potable water for human use to industrial water for mineral recovery. The rational and efficient use of water resources has became relevant in the evaluation and mine planning, since the exploration phase to closure, once Read more... about Groundwater Flow Modelling Applications in Mining: Scopes and Limitations

Closure options under consideration at some sites include backfilling mined-out pits with waste rock. Backfill may include mineralised and non-mineralised waste rock. Following groundwater rebound, flow-through conditions may develop in the pit post- closure. The backfill located in the Read more... about Backfilled Pits – Laboratory-scale Tests for Assessing Impacts on Groundwater Quality

Groundwater interaction is recognised as one of the key variables influencing slope design and management and is particularly significant in weaker rock masses. Understanding groundwater and pore pressure behaviour in rock masses is generally based on accepted theory related to flow through Read more... about Implications of groundwater behaviour on the geomechanics of rock slope stability

Mining throughout the world has entered a new phase.  Larger mines, higher production rates and mining significantly below the water table have dramatically increased the importance of groundwater management.  Deposits once passed over due to groundwater concerns are now being brought into Read more... about The True Cost of Groundwater

An evaluation of the surface water and groundwater systems for an existing or proposed mining project is important for almost all mines. There is either too much, too little or there are issues of managing water
quality either on the mine site or for discharge during operation and after Read more... about The importance of a good Mine Water Balance and the benefit of early data collection
