A new type of cosmic-ray experiment is under construction in the Pyhäsalmi mine in the underground laboratory of the University of Oulu, Finland. It aims to study the composition of cosmic rays at and above the knee region. The experiment, called EMMA, will cover approximately 150 m of detector area. The array is capable of measuring the multiplicity and the lateral distribution of underground ...

the political and social revolutions during recent years have made rapid changes in urban and rural life. these have created inequality in the distribution of resources and lack of congruent development among cities and rural migration in third world countries. herein, there are various techniques for assessing the rate of development in different regions one of which is analytical hierarchy me...

Oxidation of sulfide-containing ores is the main cause of Acid Mine Drainage (AMD), which is an environmental problem associated with both the abandoned and active mines. Iron-bearing sulfide minerals can be oxidized and form mine waters with high sulfate content, low pH, high electrical conductivity, high redox potential, and high concentrations of iron, aluminum, and other heavy metals. In th...

In the surface mining industry, the cost of workplace-related accidents is high in terms of downtime and equipment repair. Training operators how to safely inspect and operate their vehicles is the major part of any training program. Traditional training methods are often expensive, ineffective, or even life-threatening. As a result, the mining industry is constantly searching for better traini...

Platinum mining in South Africa is typically undertaken on thin seams having low to moderate dip and huge lateral extent. The relatively poor grades dictate a high requirement for capital, but the extent of the orebodies provides a very long life of mine in which to recover that capital. Historical mining practice has been dominated by hand operated drill and blast methods, although the industr...

Controlled recirculation has been used in the metal/nonmetal mining industry for energy savings when heating and cooling air, in undersea mining and for increasing airflow to mining areas. For safe and effective use of controlled district recirculation, adequate airflow to dilute contaminants must exist prior to implementation, ventilation circuit parameters must be accurately quantified, venti...

It is sad to have to record that the author died only a few days after going through the final proofs of the fourth edition of this standard work. This book, which deals with a very difficult and vexed subject, is increasingly in demand with the development of modern industry. It is a mine of information, a veritable encyclopaedia on the subject, and will we feel sure greatly benefit dermatolog...

The United States National Institute for Occupational Safety and Health, through an informal partnership with industry, labor, and the United States Mine Safety and Health Administration, has developed and tested a new instrument known as the Personal Dust Monitor (PDM). The new dust monitor is an integral part of the cap lamp that coal miners normally carry to work and provides continuous info...

The activities of mining exploitation in Campo de Jales were performed in an uncontrolled way and gave rise to serious environmental contamination: rubbish depositories have been accumulated with no treatment or maintenance. An investigation developed around Jales Mine showed the existence of some chemical impact originated from the waste produced during mining activities. Some "black spots" fo...
