Abstract
The researched parameters of the catching device, which
ensures the safe operation of equipment and working people in deep open
pits, where are formed the benches by steep dipping layers. For obtaining
the results, the following methods were used: analytical – in determining
existing devices for the capture of rocks; geometric – in determining the
direction of the flight of blocks, semigraphical – in plotting and analyzing
them. The modern technological catching devices, their structure,
construction are analyzed. These structures protective devices can be used
in deep pits in the development of deposits. Analytical dependence of the
height of the jump the block of rock after hitting about a horizontal surface
is improved, which takes into account the rate of falling and the angle of
rebound the block, the elasticity of the surface. Creating of catching
designs which capture the blocks of rock in the falling from the upper
horizons in open pits allows to operate safely the mining equipment and to
save the lives of workers. Especially this is important in the development
of deposits by steep dipping layers. Proposed solutions can improve the
safe using of dump trucks and moving workers in the work zone in the
mining ledges of height over 30 meters.
