APPLICATION OF PLOW MINING IN UKRAINE
The paper discusses application of plow mining in Ukraine. Both historical and present aspects of plowing technique
development have been described. Particular attention has been paid to the conditions in which application of plowing
is the most advantageous. This concerns both external and internal (e.g. mining and geological) conditions. Advantages
and problems occurring during plow exploitation are depicted in detail on the basis of theoretical and practical studies
conducted in National Mining University.

Chains – boon or bane for modern plow technology?
TThe coal plow is an essential piece of equipment for winning under thin-seam conditions. Today’s plow installations,
which deliver drive outputs of 2 x 800 kW, are equipped with chains 42 x 137 mm in size and can operate at speeds of
up to 3.6 m/s. This places huge demands on the chains and their connecting links. Small face openings, which require
low-height conveyor systems and coal plows with minimal guideway clearance, combined with the restricted amount of
space available in the gate roads where the compact drive units have to operate, pose a real challenge for the geometry
and quality of the plow chains. Achieving maximum face outputs regularly and without interruption, even when operating
with highly-stressed plow chains, calls for real manufacturing and engineering skills on the part of the equipment sup-
pliers and chain-makers combined with mining know-how and an effective preventive maintenance system on the part
of the operator.
