Переведите текст :
Mining engineers plan and direct the various engineering aspects
of extracting minerals from the earth. They prepare initial plans
for the type, size, location and construction of open pit or
underground mines.
The sorts of things that a mining engineer oversees at a mine
might include:
• conduct investigations of mineral deposits and undertake
evaluations in collaboration with geologists, other earth
scientists and economists to determine whether the mineral
deposits can be mined profitably
• prepare plans for mines, including tunnels and shafts for
underground operations, and pits and haulage roads for
open-cut operations, using computer-aided design packages
• prepare the layout of the mine development and the way the
minerals are to be mined
• plan and coordinate the employment of mining staff and
equipment with regard to efficiency, safety and environmental
conditions
• consult with geologists and other engineers about the design,
selection and provision of machines, facilities and systems for
mining, as well as infrastructure such as access roads, water
and power supplies
• operate computers to assist with calculations, prepare
estimates on the cost of the operation and control expenditure
when mines come into production
• oversee the construction of the mine and the installation of plant
and equipment
• make sure that mining regulations are observed, including the
proper use and care of explosives, and the correct ventilation
to allow the removal of dust and gases
• conduct research aimed at improving efficiency and safety
in mines
• establish first aid and emergency services facilities at the mines.
