Description
Summary:Results of design and analysis of system to transport equipment in uncased boreholes drilled from underground excavations are reported. A thruster is a pneumatic percussion device. The optimal parameters of the transport system operation in various conditions are determined. Using mathematical description of movement of thruster in well, the authors derive relations for the thruster velocity as a function of various initial data.
