Comprehensive Framework

Changing climate conditions affect mining operations all over the world, but so far, the mining sector has focused primarily on mitigation actions. Nowadays, there exists increasing recognition of the need for planned adaptation actions. To this end, the development of a practical tool for the assessment of climate change-related risks to support the mining community is deemed necessary. In this study, a comprehensive framework is proposed for climate change multi-risk assessment at the local level customized for the needs of the mining industry. The framework estimates the climate change risks in economic terms by modeling the main activities that a mining company performs, in a probabilistic model, using Bayes’ theorem. The model permits incorporating inherent uncertainty via fuzzy logic and is implemented in two versatile ways: as a discrete Bayesian network or as a conditional linear Gaussian network. This innovative quantitative methodology produces probabilistic outcomes in monetary values estimated either as percentage of annual loss revenue or net loss/gains value. Finally, the proposed framework is the first multi-risk methodology in the mining context that considers all the relevant hazards caused by climate change extreme weather events, which offers a tool for selecting the most cost-effective action among various adaptation strategies.

Mining And Smelting

AbstractMetals have been central to the development of human civilization from the Bronze Age to the present although historically, mining and smelting have been the cause of local environmental pollution with the potential to harm human health. Despite problems from artisanal mining in some developing countries, modern mining for Western standards now uses the best available mining technology combined with environmental monitoring, mitigation and remediation measures to control emissions to the environment. The relocation and removal of large quantities of mineral and waste could also release chemicals into the environment including surface water, ground water and soil during the mining lifecycle. There are only few published methods available for prioritizing hazardous chemicals. These fail to recognize differences between organic and inorganic chemicals make it necessary to develop separate screening and prioritization procedures for those two different classes of chemicals. In this study, we focus on the development of screening and prioritization procedure in risk assessment for inorganic chemicals with particular reference to those used, generated and released in mining operations.

Geotechnical Risk

Abstract Underground mining activities are prone to major hazards largely owing to geotechnical reasons. Mining combined with the confined working space and uncertain geotechnical data leads to hazards having the potential of catastrophic consequences. These incidents have the potential of causing multiple fatalities and large financial damages. Use of formal risk assessment in the past has demonstrated an important role in the prediction and prevention of accidents in risk prone industries such as petroleum, nuclear and aviation. This paper proposes a classification system for underground mining operations based on their geotechnical risk levels. The classification is done based on the type of mining method employed and the rock mass in which it is carried out. Mining methods have been classified in groups which offer similar geotechnical risk. The rock mass classification has been proposed based on bulk rock mass properties which are collected as part of the routine mine planning. This classification has been subdivided for various stages of mine planning to suit the extent of available data. Alpha-numeric coding has been proposed to identify a mining operation based on the competency of rock and risk of geotechnical failures. This alpha numeric coding has been further extended to identify mining activity under ‘Geotechnical Hazard Potential (GHP)’. GHP has been proposed to be used as a preliminary tool of risk assessment and risk ranking for a mining activity. The aim of such classification is to be used as a guideline for the justification of a formal geotechnical risk assessment.

Americans like to buy things and own them—barbecues and refrigerators, computers and iPods, cars and bikes, boats and even private planes. Some folks make their appliances last a long time, but manufacturers rely on most people to buy new ones every five years or so. The few critics of our system sometimes charge that items from appliances and vehicles are designed to break down relatively quickly, to prod consumption along. Walking through a showroom or past shop windows, how many people stop to wonder where all the stuff comes from or what happens there? Here is the short answer: Nearly everything you use every day is based on minerals mined somewhere, often leaving behind disfigured land and a toxic mess. Materials still mined in the western United States include metals, particularly gold, iron, copper, zinc, and molybdenum—plus gypsum, borates, and other salts, and most cement ingredients. Mining is the prow of America’s consumer-propelled ship. Its whole purpose is to dig up resources for transformation to consumer goods. But the resources are nonrenewable, so mining progressively eliminates and eventually exhausts them. The processes of exploring for and exploiting mineral deposits consume vast resources also, especially water and energy. Natural processes spread mine pollution into water, soil, and air, at times killing all life in creeks, streams, and reservoirs. Geographer Lewis Mumford once estimated that “Mining’s effects on the earth are now on the same scale as hugely destructive natural forces.” He guessed the minimum amount of material moved by global mining operations at 28 billion tons in 1963—nearly twice the sediment all the world’s rivers carry annually. Determining just how much land may be affected by mine wastes, and how much farther the damage might spread, is more dif- cult. The massive scale of today’s mining operations dwarfs Mumford’s figure. The dominant U.S. mining law offers wide swaths of U.S. public lands to any and all comers, whether foreign or domestic (box 4.1).

Classic Paper

Ideas about the prehistoric past have for long been based upon pieces dug from the mounds and hollows which are the remains of man’s activities. Only recently has it been clearly realized that monuments are continually being modified by nature and that evidence of weathering, denudation and silting can be as informative as the artifacts sometimes found in them. A recent conference showed that there was relatively little exact knowledge of how such processes take place and, in particular, of their quantitative aspects. As has been recently emphasized archaeological excavation is a means of investigating the truth of an hypothesis by destructive analysis. It thus emerges that any study of the action and interaction of natural processes affecting a prehistoric monument must clearly involve the converse, i.e. a monument must be built and studied, in all its component parts, under controlled conditions. Today an impressive and substantial ditch and bank, cut into and heaped upon the chalk of Overton Down in Wiltshire, stands a shining witness to the execution of this principle.The work of construction was undertaken with hand tools, but not all of these were modern picks and shovels. A part of the bank was dug and heaped with primitive tools and appliances—antler picks, shoulder-blade shovels and wicker carrying-baskets. It has long been known (from the not infrequent discovery of examples apparently discarded) that antler picks were the primary digging tools of those who dug the ditches and heaped the long and round barrows, the causewayed camps, the henges and the cursuses, but precise appreciation of the real potentialities of antler picks was slight. Greenwell and Pitt Rivers commented upon the use of such implements, while the subject was pursued in some detail by Horace Sandars in his paper On the Deer Horn Pick in the Mining Operations of the Ancients, among others. Curwen’s accounts of the Sussex flint mines further stimulated such studies as did Clark and Piggott’s classic paper. From Sandars’s, Curwen’s initial and subsequent study and from summaries of the past two decades the view emerged that the antler picks were almost invariably used as punches and levers to break up chalk. Thus, such thought as has been given to prehistoric mining and digging has been to some extent inhibited by acceptance of that notion.
