The methodology currently in use that is approved by the Ministry of Environment and Waters in “ Methodological guidance for the scope and content of reports on past contamination damages at privatization” (1998) does not provide opportunity to assess impacts on landscape that are the main geo-ecological damages typical for opencast mining. In the present paper methodological approaches based on theoretical formulations and practical experience adopted both nationally and internationally related to assessment ...

The termination of mining and processing of uranium ores lead to either conservation or liquidation of uranium industry projects in a lot of countries, including Bulgaria. The liquidation of uranium industry is a problem of interdisciplinary character where problems of medicine, dosimetry radiochemistry, radio-physics, management, economics and engineering interface. All these topics define the radio-ecological engineering as a part of ecology divided into two main branches: recreation at technogenically elevated ...

Paper has show explorations of negative causes of underground coal gasification impacts to environment. Also is given view on importance of exploration on conquering technology of underground coal gasification in concrete deposit conditions.

The National Agency for Mineral Resources (NAMR) is the competent authority that is responsible on behalf of the Government of Romania to manage Romania’s mineral resources and to enforce the provisions of the Mining Law and related regulation concerning the prospecting, exploration, exploitation and capitalization of mineral resources deposits. NAMR has the obligation to monitoring the application of the measures established with regard to the protection of the soil and subsoil during and after the mining activ...

With the general trend toward larger blasts in mining, ground vibration and air blast problems and complaints have significantly increased. With increasing environmental constraints on the levels of disturbance induced by blasting operations upon nearby residents, there is an increasing need to be able to design cautious blasting with greater precision. Therefore, determination of maximum amount of explosive per delay for a certain distance especially in large blasts is of great importance for the elimination of t...

In the reports are considered the problems of analytical description the processes of geomigration of pollution of underground waters and building up the special system of hydrogeological researches as a part of general system of geoecological monitoring . The basic mathematical models of a filtration and masstransfer are considered and analysed which can be used for exposition of migration of hydrocarbons in underground waters.

Republican unitary enterprise (RUE) PA ”Belaruskaliy” is one of the most largest world producers of potassium fertilizers. Significant volumes of production expect a significant negative influence on the environment. This report has its aim a showing of the forms and methods of participation of mine surveying service of PA ”Belaruskaliy” in realization of program “Ecological politicians of enterprise”.

When carrying out the activities, related to the exploration, operation and processing of uranium ore in Bulgaria the environmental protection was not among the priorities. As a result of many years of industrial activity the technogenically increased natural radiation background in some regions has reached significant levels and the chemical pollutants has threatened the pools with clean water and the ground surface. The cessation of work for uranium mining and milling was done in a hurry, without preliminary pre...

The Zlataritsa river is located in the South-western part of Bulgaria and mouths into the Mesta river. The Zlataritsa river passes through Eleshnitsa settlement where mining sites for exploitation and treatment of uranium ore are located. This paper presents the river pollution of uranium and radium as a result of mining activities in the examined region. The data used are for three periods - during the complete productive engagement, during the technical liquidation and after the end of technical liquidation. The...

Under the effective legislation of the Republic of Kazakhstan, Stratal underground waters after uranium mining from stratum-infiltration deposits subject to rehabilitation to initial state. In this connection, the 13- years test with respective monitoring of aquifer on Irkol deposit has been done. Observations have proved that ore-bearing aquifer area of about 20000 square meters is almost rehabilitated to its initial hydro-chemical state. To intensify strata waters restoration, method of forced solution drawing t...
