Reclamation and Revegetation for Mines in Arid Climates is intended for environmental specialists in private practice and governmental agencies. The purpose of this course is to present mining related reclamation based on practical and actual experience. The course presents actual mine reclamation practices that worked or didn’t work. The focus of this course is on base and precious metal mining operations in the western US, but the reclamation practices are applicable in other regions of the US and abroad. The course presents all aspects related to reclamation of mines from the initial baseline studies to final reclamation and bond release. Much of the approach is based on requirements by governmental agency rules and regulations. Reclamation programs are based on site specific conditions and baseline studies. These studies and surveys may start by examining natural revegetation in the region and on old mine disturbance. The goal is to create systems based on ecosystem analysis (prior knowledge) and sound ecological processes and patterns. The ecosystems established will be stable and sustainable based on the environmental settings, since local ecosystems are a function of climate, soils, biota; animals/vegetation, time, cycles, and energy flow. The goal is to match current ecosystems and promote diversity in compatibility with the surrounding landscape.

In theory, mine closure is simple; in practice, it is difficult. In this course, we will start with the simple and then proceed to the more difficult, which we will explain in terms that will enable you to deal with the many issues that arise as you plan and implement mine closure. The simple part of mine closure may be set down as three objectives: remove equipment and structures; stabilize waste piles; and control spread of pollutants from the closed site. As we shall see as we progress through this course, these three simple objectives quickly give rise to many questions and knotty issues, including: Who pays? Who says enough is enough? And, What is to become of the site in the long term? Many more related and difficult issues arise. Reading only this course will not enable you to solve all the problems. Each mine site is unique and demands a unique closure plan and approach. You will undoubtedly have to formulate the specifics of the closure plan for your mine by way of many studies, meetings, reports, and deep deliberations. This course will attempt to set down the current state of ideas, practice, and possibilities, so that you are empowered to move forward to success at the mine where you are part of a team charged with mine closure.

Regardless of world market conditions, to win, sustain, and maintain the right to mine is all about sustainability. Waste water management is emerging as the pre-eminent sustainability issue within the global energy and mining resource industries, i.e. related to the following activities: coal bed methane water (CBMw), LNG waste water, oil shale water, coal mining, open pit and underground mining, natural gas extraction, hydrocarbons, metallurgical ore processing, surface and underground earthworks and drainage, and underground coal gasification. This waste water management course has been designed to educate people from the mining, metallurgical, oil, and gas sectors who have to manage waste water issues associated with their day to day activities. This course will equip them with a basic knowledge and understanding of water management tools and strategies, including knowledge of the common terms associated with the water treatment industry. The course does not replace professional advice; however, it does allow informed discussions with professionals. Traditionally, waste water management is encountered in most energy resource extraction, mining, and ore processing activities. All of these industries are facing increasing scrutiny, regulation, competition for land access, and "angst" from local landholders (farmers) and stakeholders (agricultural and urban development). These crucial stakeholders have the perception of their water resource being potentially polluted, and/or reduced in available volume by the resource industry unless proved otherwise. They are concerned about sustainability, potential pollution issues, and access to the water resource itself. Water is the principal vehicle by which potential pollutants in untreated wastewater can be carried from these industries to local habitats potentially impacting on the local surface areas, the local environment, and underground aquifers—especially where this water is accessed and applied through traditional practices such as irrigation. In extreme cases, the polluted water could impact on human life itself. So, in order to demonstrate responsible stewardship over the water resource being extracted, this course gives a practical framework in order to create a robust sustainable water management solution (plan) that has the components of assessing the: raw waste water quality; final stage target water quality; potential beneficial uses for the water; treatment options to achieve the targets outlined above; and a risk assessment process that avoids harm to the environment while realising long-term sustainable benefits.

This course discusses the principles and practice of surface water management at mines. It describes best management practices for surface water management at a mine in order to achieve the following objectives. Control surface water in order to prevent pollution of on-site and off-site water resources. Divert excess runoff that may otherwise flood or interfere with mine workings. Limit infiltration to mine waste disposal facilities to control potential pollution of surface water and underground waters resulting from excessive infiltration. Control erosion of the site to limit sediment runoff that may negatively affect receiving waters. Control erosion that may otherwise cause excessive damage to mine closure works. Objectives All mines disturb the surface. All mines change the features of the mine site that affect precipitation runoff, evaporation, streamflow, and erosion. All mines involve grading of the site, diversion of runoff, and placement of wastes that increase or decrease infiltration of surface water to the groundwater. Inevitably at a mine it is necessary to capture and control sediments and other pollutants in surface water, and build and operate the works needed to comply with regulations regarding off-site impact by surface waters running from the mine. Accordingly, this course is intended for all those people at a mine or associated with a mine who may be involved with or responsible for the hydrologic, hydraulic, environmental, civil, and mining engineering works required to manage surface water at a mine.

A tenet of investment is that if the risks of an investment are high, then the investor should be compensated for assuming the risks by a high potential return from the investment. However, quite often the risks associated with an investment are not known or understood. The results vary but may include an investment evaluation that is not representative, a bad investment decision, and low returns or even losses. Inadequate technical or financial information is the main reason risks are not taken into account or are misunderstood. Unfortunately, lack of such information is a common situation in mining and other large industrial projects. No amount of investment evaluation or analysis can compensate for lack of information. If the risks are known and can be characterized in some way, methods of investment analysis can be used to provide a quantitative assessment of the risks. One goal of this course is to describe methods for risk quantification, their advantages and limitations, and to give realistic (if not real) examples of their application. Fortunately these methods are simple so that complete evaluation of an investment is (or at least should be) a simple process.

In this course, we focus on groundwater theory and practice applicable to mines and the specifics of open pits, shafts, underground mine workings, heap leach pads, waste rock dumps, and tailings impoundments. We discuss, for each of these facilities, the principles of groundwater and facility design & operation that apply and must be implemented to control and protect groundwater and surface water. This course is one of a series of related courses, some of which are still in development, including Groundwater in Mining Surface Water Management at Mines Mine Water Balance Analysis Authors Jack Caldwell   Duration 14 Hours Access 90 Days Category Geotechnics Level Specialize Version Date January 22, 2016   ​Need to train a team?
