Abstract. The paper presents experience of using a hydraulic giant for the rock destruction in the process of amber extraction.

It is stated that the hydromechanical method increases productivity of the amber extraction from the sand and clay deposits and reduce negative impact of open cast mining on the environment. The process can be essentially intensified by way of vibratory excitation of the rocks in the deposit. This fact is confirmed by results of different studies, which show that speed of the amber particles floating up is significantly increased when lower sand layers are under the action of vibroexcitation. The process of vibrating-and-boiling bed formation is affected by such parameters as amplitude and frequency of oscillation, magnitude of disturbing force, geometry of vibroexcitation sources location in the bed, water or air pressure at a complex impact. Basing on the research results, the authors present graphical dependencies between speeds of the amber particles floating up and various vibroexcitation frequencies of the hydraulic air-and-sand mixture containing amber inclusions. Besides, the authors determined and recommended operating ranges of the mixture-vibroexcitation frequencies and amplitudes for various mixture densities.

Keywords: hydraulic giant, sand bed, amber, sand bed vibration disturbance.
