Modeling the process of hydromechanical amber extraction

The paper represents a process of hydromechanical amber
extraction modeling to obtain input data and substantiate operation
parameters of mining equipment to develop the improved
hydromechanical technique of amber extraction. Intensification of amber
mining process is possible when sandy deposit is saturated by water and
air. Moreover, mechanical impact by means of vibration is added. Amber
displacement within sandy deposit is considered. The deposit is
characterized by environmental resistance when influence factors act on
the process of amber surfacing. Amber concentration distribution over a
deposit surface involving determination of floating periods of different
amber fractions in terms of different operation modes as well as computer
experiment concerning the amber grades and its distribution over amber-
bearing deposit involved the use of computer environment Matlab.
Adequate mathematical model to solve one-dimensional boundary
problems for systems of parabolic and elliptic differential equations
within partial first-order derivatives on one spatial variable and time has
been developed. The model describes accurately the behaviour of
different amber fractions within amber-bearing deposit in terms of
vibration effect as well as water and air supply.
