site and delivery aspects, excavation plan etc. Today modern mine will use
computer programs and have a facilities stock and several servicemen. Equip-
ment quality, standardization, ease of maintenance, regular delivery of spare
parts and training of servicemen make the service operation cost-effective and
fast. Standardization of equipment results in having several parts of the same
type, so it reduces the number of different components that need to be stocked.
Задания
1. Переведите текст.
2. Ответьте на вопросы к тексту:
a) What does standardization of equipment result in?
b) When may maintenance be handled by one or two persons?
c) What does the modern mine use?
3. Переведите на английский язык следующие предложения:
a) Сырость и мелкая пыль создают в руднике разрушающую обста-
новку для соединений и незащищенных частей машин.
b) Стандартизация оборудования позволяет использовать меньшее ко
-
личество необходимых деталей.
c) Для сервисных работ требуется набор инструментов и необходимых
(critical) запасных (spare) частей.

Mine development
Mine development is the excavation work done before starting full scale
extracting of ore in a mine or stope. In most cases, development excavation con-
tinues throughout the life of the mine. Development objects are vertical shafts,
horizontal drifts, inclined ramps and steep raises. Drilling and blasting rock ex-
cavation is usually used with exсeption of raises.
The extent and type of development work required depends on the depth,
size and geology of the ore body, on the chosen mining method and expected
life of the mine. Caving methods in particular demand substantial development
