INTRODUCTION There is still interest in a unified methodology to quantify the mass of particulate material emitted into the atmosphere by activities inherent to open-pit mining. For the case of total suspended particles (TSP), the current practice is to estimate such emissions by developing inventories based on the emission factors recommended by the USEPA for this purpose. However, there are d...

Coal mines is one of the major source of energy in India, but its surrounding environment is very toxic to the persons living near these plants. A small case study has been done with relation to GIT problems and related disorders of the miners. In this study 200 people were selected including male and female and they were divided according to their age. Questionnaires related to GIT problems we...

investigations were carried out on coal tailings by conventional cell and column flotation techniques. tests were conducted to assess processing coal tailings of alborz markazi coal washing plant in iran by column flotation. the effects of reagent type/dosage were investigated with conventional flotation and their results were used in the performance of column flotation. also the effects of the...

Concern about the production in mine waste dumps of acid drainage water containing high levels of sulphate and metal ions initiated the research of this project into the possibility of chemically inhibiting the bacteria responsible for the acid formation in the dumps. Research in the U.S.A. indicated that such treatment of dumps might be effective. Two types of dump have been investigated, name...
