The Study of the Gas Dynamic Regime of a New Open Salt Mine Turda, Valea Sărată

The opening of any underground mining work requires a check and the establishment of the regime of explosive and toxic gas emissions (methane and carbon dioxide). Establishing the regime of gas emissions is necessary to clearly establish the correct choice of specific machinery in construction Ex. or not, as well as the correct sizing of the vent. The purpose of this paper is to determine the rate of methane (explosive gas) and of carbon dioxide (axphysants gas) in the mine workings of Valea Sărată salt mine newly opened salt mine. For the preparation of the documentation, the following elements were taken into account: -The geological conditions of the salt deposit in the Valea Sărată mining perimeter;

-Existing records and documentation regarding previous occurrences of gas and their manifestation;

The results of quantitative and qualitative measurements in underground mining works, regarding:

-circulated air flows;

-gas concentrations: methane, its counterparts and carbon dioxide;

Establishing the release of gases in the underground atmosphere of the mining works. Based on the measurements and observations made, as well as the analysis of the previously mentioned elements, the underground mining works were included.
