MY DISSERTATION
════════ In a period with 1997 on
2000 theoretical and experimental researches of the turbulent flooded water
stream works on washout of sandy ground in the terms of subbottom face at the
submarine sands mining were conducted. On results the researches was written dissertation

════════ The thesis is devoted to the question of development of methods for
accounting rational parameters of the worker
member of unit for ecologically sparing extraction of alluvial
minerals. The perspectives of using the ground-extraction body with hydraulic
loosener, allowing to take ground from under a bottom surface during submarine
mining of alluvial minerals from depths up to 100m, are grounded.
The process of incoherent ground loosening by a water
jet in constraint conditions under bottom surface and interaction of processes
of ground loosening and pulp suction are investigated. As a result of
theoretical and experimental researches, the analytical expressions for
determining geometrical parameters of underbottom loosening zone and also the
analytical expressions allowing to rationalize the process of ground extraction
by the worker member with a jet transport pump are obtained.
The engineering technique for calculation of a worker member
loosening system▓s parameters is developed. The loosening system of the new worker member
is designed with use of the mentioned technique. The successful industrial
tests of the worker member are conducted.
Key word: submarine production, ecologically sparing
method, worker member, under-bottom extraction, hydraulic loosening, incoherent
ground, washout zone.
