EVALUATION OF PILLAR STRESS STATE ON MINES «APATIT»
The values of the stresses in the pillars between the approximated parallel horizontal
entries at developing apatite-nepheline ore deposits "Apatite", depending on the depth of
work and pillars size. The calculation was performed taking into account the tectonic stress
field acting in the array and the reference pressure, which is formed at the time of block.
Key words: arch, numerical simulation, the effect of treatment works, tectonic
stresses, bearing pressure.

DEVELOPMENT TESTING HYDRAULIC-PULLER OF HIGH PRESSURE
A test bench was submitted and tests by defining dependences characterizing working
condition and allowing substantiating of rational parameters for hydraulic-puller of high
pressure were described. Results of development testing hydraulic-puller were analyzed and
dependences of friction power loss from increasing pressure were ascertained.
Key words: water-jet technology, development testing, hydraulic-puller, power loss,
pressure.
