摘要：Patterns of interrelation between the ambercontaining mining mass and vibrohydraulic intensifier were defined with the substantiation of its technological parameters for creating the required density of the medium, which provides for maximal extraction of amber.Existing methods and methods for the extraction of amber were analyzed and a new method for the extraction of amber out of ambercontaining sand field was proposed, providing for higher efficiency of its recovery while negative impact on the natural environment is reduced.Laboratory and field studies were carried out on ambercontaining sand fields in RivnenskyVolynsky region with the purpose of improvement of existing technologies of extraction of amber. When carrying out experimental research, we determined the main technological parameters of hydromechanical method of amber extraction and determined the patterns of influence of water and air on the liquefaction of ambercontaining sandy media when an array is exposed to the action of a vibrohydraulic intensifier, during which a maximal speed of amber recovery to the surface is achieved.In the process of field research, we implemented the latest technology and achieved maximum extraction of amber in the deposit, which is 90–95 % of the total mass.
