Underground mining, by its nature, presents a range of health and safety hazards that are different from those in other sectors. Some hazards, such as ground instability, are inherent in the underground environment. Others are introduced through complex mining activities and processes, which bring potential hazards into the underground

Acquiring a representative gold sample is seldom easy and in almost all cases sample results need a large measure of interpretation. Some of the underlying reasons why mining geology sampling is difficult are Large particle sizes to be sampled with. A representative sample should contain all of the constituents of a deposit and in exactly

Gold in Maine. Gold occurs in several geologic environments in Maine in bedrock, in sediments that were eroded from bedrock by glaciers, and in stream deposits derived from either of these sources. Veins of gold in bedrock are called 34lode34 deposits, and 34placer34 deposits are concentrations of gold that accumulated in unconsolidated sediments.

A quantitative rockburst hazard assessment procedure was introduced on Elandsrand Gold Mine at the end of 1994. It is currently used to evaluate the seismicityrelated risk in production areas on the mine. Six parameters related to seismicity, geology, mining layout, and production are rated and results are used as a planning tool on a regular

Gold deposits are found in different types of rocks and geologic formations, falling into two mining categories lode primary and placer secondary. Lode deposits are contained within surrounding rock whereas placer deposits are dust particles contained in streams and stream beds. Geographically, gold can be found

From what we learned so far, we can say that mining is a very high risk business, from both the safety and economic point of view. Slope stability is one of the major sources of risk, and hazards arise in several ways, from an incomplete knowledge of geological conditions, and an incomplete knowledge of damage caused by mining processes, or an

Historically, mercury was used extensively in placer gold mining in order to form mercurygold amalgam with smaller gold particles, and thereby increase the gold recovery rates. Largescale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and smallscale gold mining ASGM, often clandestine, gold prospecting.

Gold is relatively scarce in the earth, but it occurs in many different kinds of rocks and in many different geological environments. Though scarce, gold is concentrated by geologic processes to form commercial deposits of two principal types lode primary deposits and placer secondary deposits.

Early goldproducing districts, some mining gold as a byproduct of other metals, included Tintic, Bingham, Mercur, Park City, Gold Mountain, Gold Springs, State Line, Clifton, Park Valley, Spring Creek, American Fork, and San Francisco. During these early years of discovery, thousands of claims were filed and many mines started.

The United States Geological Survey has published lots of reports about general geology and mineral resources for most of the major goldproducing areas. In addition most state geological surveys where gold production has occurred have compiled reports and maps to document the general geology, deposits and mining activity.

Gold has been treasured since ancient times for its beauty and permanence. Most of the gold that is fabricated today goes into the manufacture of jewelry. However, because of its superior electrical conductivity and resistance to corrosion and other desirable combinations of physical and chemical properties, gold also emerged in the late 20th century as an essential
