ABSTRACT

This article deals with the measurement and the setting up of the main mine ventilator in
CSM mine – South by means of laser measurement. CSM Mine – South is located in the
eastern basin of Karviná, in the mining district of Ostrava-Karviná near
the village of Stonava.
According to the Ordinance no. 22/1989 Coll., as subsequently amended, every mine
has to have a separate ventilation system. Mechanical ventilation provides appropriate
working conditions and prescribed composition of air in mines. Ventilation is carried
out by the main mine ventilator (MMV) located at the main mine. For safety reasons,
every mine has to be equipped with a backup MMV. Functionality of both the main and
the backup mine ventilator has to be checked on a regular basis (generally by the
manufacturer of the MMV). One of the most important parts of these inspections is the
measurement of the geometry and the alignment of the gearing and the ventilator. These
measurements are currently carried out by means of the latest laser equipment. Some of
its most notable advantages are a very high accuracy, speed and a simple reproduction
of the measured values. Measurement of the geometry of the MMV on the main CSM –
South was held in October 2011. It was carried out by EasyLaser E710 measuring
equipment. Both the first and the second check measurement resulted in values which
complied with the maximum deviation of 4 mm required by the manufacturer of the
MMV. The measured values were 1.23 mm in the horizontal direction (parallel offset)
and - 0.56 mm in the vertical direction.
In consideration of the measured values that met the required accuracy, the main mine
ventilator on the mine CSM - South was recommended to be put into operation.
