ABSTRACT
Purpose.To specify parameters of the relationship between sandy rock and vibrohydraulic intensifier as well as to justify the use of hydromechanical method to intensify amber extraction.
Methods. The basic laws of surface amber extraction processes from sandy amber deposits using hydromechanical method with vibrohydraulic device were experimentally studied. Analytical studies were performed using differential and integral calculation, experimental studies involved methods of mathematical statistics.
Findings. Parameters of the relationship between sandy rock and vibrohydraulic intensifier have been established by detecting the intensifier amplitude, frequency, rock density, water and air supply into the massif, which allows to create a continuous suspension medium and increase amber mining productivity.
Originality. For the first time, the research has established the influence of vibration, water and air on the liquefaction of sandy media which is achieved by vibrohydraulic dredger in the natural environment, depending on the intensity of gas-liquid mixture feeding into the amber containing massif. It was established that water and air consumption is directly proportional to the volume of the working space, penetration rate; medium porosity, density and moisture content.
Practical implications. As a result of the research, efficiency and effectiveness of hydromechanical method of amber extraction from deposits has been proved; the vibrohydraulic dredger for amber extraction from sandy deposits has been manufactured. Technical novelty of this device is confirmed by patents of Ukraine; the technique of vibrohydraulic device engineering design is worked out.
