Radionuclides are released as dust during mining or from exposed waste rock stockpiles where they are least containable (and mostly airborne). Radiation can also leak into the ground, and nearby water sources after they have been separated into tailings, if the tailings are not stored safely.

The Borden gold mine (formerly Borden Lake Project) is located in Chapleau, Ontario, Canada. Fully owned and operated by Goldcorp, it is the first underground mine in the country to replace all diesel mobile equipment with battery-electric vehicles (BEVs). Originally discovered by Probe Mines, the gold mine was acquired by Goldcorp in March 2015.
Mining operations: the deposit will be mined as an open pit using a conventional shovel and haul truck operation. The key mining operations include drilling and blasting, overburden stripping and mine pit establishment, excavation and haulage of ore and waste rock from the pits, and establishment of waste rock dumps and ore stockpiles.

The mill will continue to receive ore from the Urucum North open pit and from stockpiles, Great Panther said. "We are working with our consultants to make …
0.02% U (i.e. water from the mine pit, runoff from the ore stockpiles and mill site, process water, and tailings water). The 'Non-Restricted Release Zone' comprises undisturbed areas and waste rock dumps with less than 0.02% U. Water from the non-RRZ is allowed to overflow into tributaries of Magela Creek, north of the mine site,
Stockpiles shall be removed from a mined area of the pit within four (4) years from when the time normal extraction process is terminated; 6. Final reclamation shall commence after the removal of the final stockpile and shall be finished within one year from the time of the stockpile removal or the time required for removal of stockpile as set ...
Calculating Stockpile Capacity: Once the minimum storage capacities which will assure maximum mill output are known, the appropriate stockpile configuration must be determined. Stockpiles fall into two general categories: conical and elongated. Conical Stockpiles The conical stockpile is the simplest and easiest to analyze. The total stockpile capacity is given by: 3.14 (Tan A)R³ D/3000 ...
Underground mining has the potential for tunnel collapses and land subsidence (Betournay, 2011). It involves large-scale movements of waste rock and vegetation, similar to open pit mining. Additionally, like most traditional forms of mining, underground mining …
Open Pit Mining Fleet Management System. ... GroundHog Open Pit FMS uses Open APIs that easily integrate with 3rd party mining software providers, including SAP, ... Manage Stockpiles: Mines can easily track material flow from each bench to a stockpile or to the hopper to meet a mill's blend plan. Drill operators scan sample bags for tighter ...
Chile is the world's leading producer of copper, with a market share of 26.8% and accounting for approximately 10% of the gross domestic product. Given the importance of this industrial sector in the country, mine planning is a fundamental tool for achieving strategic, tactical and operational goals. This paper proposes methods to solve the problem of scheduling production in mining ...
Complex multi-parameter optimization. MiningMath maximizes the NPV for any open-pit mining project, based on an imported multi-mine block model.The cut-off grade policy and mining phases definitions are now a consequence of a modern global optimization process, given a wide set of realistic mining constraints, such as operational, processing, and socio-environmental requirements.
In each period, the mine planning decisions include which material will be excavated, and where the excavating equipment and stockpiles will be located. For a long-term schedule, these periods could be one year in length. The process for creating a borrow-pit is …
Financial Modelling of Stockpiles in a Mining Project. For many mining projects, the open pit/cut mining process often begins months or even years before the milling plant starts operating. The build-up of stockpile requires careful treatment to ensure the right grade of the ore milled is modelled and that the right value of this stockpile is ...
Operate and conduct drone surveys in accordance with slope monitoring, incident surveys, stockpiles, pickups, dam tail and Infrastructure surveyors. Conduct and report weekly open-pit scanning progression and volume. Attend daily prestart and meetings in accordance with onsite safety practices and mine production target meetings. Requirements:
The artificial stockpile should be placed in a peripheral area of your model to not affect the open-pit schedule. Avoid borders to prevent any geotechnical issue, which will impede mining the artificial stockpile completely.
Mine site volumes are precisely measured for the exact date and time of the satellite photos. The volumes can then be balanced between mine pits, ore stockpiles, leach pads, waste dumps and tailings beaches. Pre-blast surface on the left. Post-blast surface on the right. Enables direct calculation of the blast heave volume increase.
The North Mine Area hosts the Santa Rita open-pit that currently measures 2.8km-long and 1,350feet-deep, as well as the leach ore stockpiles, waste rock stockpiles, the sulphide extraction, and electrowinning (SX/EW) plant and the Ivanhoe concentrator.
open pit mine production scheduling (opmps) is a decision problem involving which blocks, within the final pit limits, should be mined in each year, and where the blocks should be sent, e.g., mill, waste dump or stockpile, to maximize the net present value (npv) subject to the constraints that: (i) mining and processing consume limited resources …
The ground used for the stockpiles - It should be firm and provide a stable foundation. It should be relatively level, properly drained and should not be affected by water courses, which may flood. The volume of product. - The output of a quarry will have an influence on the siting, type and size of stockpile.
MINING AND MILLING - OPEN PIT TAILINGS DISPOSAL Tailings must be disposed of in a manner that optimizes protection of human safety and the environment. On-land tailings impoundment systems must be designed and constructed in accordance with internationally recognized engineering practices, local seismic conditions, and precipitation conditions.
Guidelines for Mine Waste Dump and Stockpile Design is a comprehensive, practical guide to the investigation, design, operation and monitoring of mine waste dumps, dragline spoils and major stockpiles associated with large open pit mines. These facilities are some of the largest man-made structures on Earth, and while most have performed very well, there are cases where instabilities have ...
Pit designs were created based on the current mining methodology that includes mining at 5m or 10m benches. Ramp and pit access designs considered the largest envisaged hauler dimension specifications ensuring safe and practical execution. Pit designs were conducted based on the optimum pit shell.
We consider stockpiles as part of our open pit mine scheduling strategy, propose multiple models to solve the OPMPS problem, and compare the solution quality and tractability of these linear-integer and nonlinear-integer models. Numerical experiments show that our proposed models are tractable, and correspond to instances which can be solved in ...
