Managing the Dust Degree –Related Risks in Valea Jiului Collieries: A Synthesis

The paper aims to make a synthesis regarding the risks associated with the presence of industrial dust in the underground atmosphere of the coal mines. Thus, in the first part of it are presented relevant aspects regarding the health risk associated with the exposure to silica dust, as well as the flammability and explosiveness of the coal dust, in correlation with the mechanism of the explosion. The second part is dedicated to identifying and substantiating measures to combat the explosiveness of coal dust. In presenting the mentioned measures, the emphasis is placed on highlighting the scope and the specific advantages and disadvantages of each measure, with particular emphasis on the possibilities offered by the use of less employed techniques in mining operations in the Jiu Valley, such as it is, for example, the treatment of mining works with hygroscopic substances. The purpose of the authors is to offer the experts in the field of management of occupational safety and health in the mining industry an overview, in conjunction with specific information elements that facilitate the decision-making processes regarding the minimization of the hazards associated with the degree of coal dustiness in the Jiu Valley collieries.
