Вскрытия в процессе добычи руды называются забоями. Есть вскрытия: подготовка блоков руды к извлечению и производство (непосредственно вскрытие). Технологии сегодня достигил такого уровня, что золото извлекается с глубины 40000 (не видно единицы измерения из-за знака "поворот картинки") и глубочайшие шахты достигают 700 метров. Именно механизмы обеспечивают мощь и обученные шахтеры, интеллектуализирующие процесс, востребованы сегодня для успеха в этой высоко конкурентной отрасли промышленностиОбъяснение:
It is summer. Mother duck has got six eggs. Five eggs break and five yellow ducklings come out. But the sixth egg doesn’t break. "Oh dear! This egg is very big," says mother duck. Later, the sixth egg breaks. A big grey duckling comes out. "Oh no! This duckling is ugly!" shouts mother duck. "Come on, ducklings. Let’s go and visit the hen," says mother duck. She looks at the ugly duckling and she says, "Walk behind your brothers and sisters. I don’t want anybody to see you. You’re ugly!" The ugly duckling is sad. The hen sees the ducklings. She sees the ugly duckling too. The hen laughs. "Look! That duckling is silly!" says the hen. "He has got short legs. He’s grey. His beak is silly. He’s an ugly duckling!" Everybody laughs. The ugly duckling is very sad.

Dear Kate,
Thank you for your letter. It was nice to hear from you. Sorry, I haven't written for so long because I had an exam.
So, you asked me to tell you about holidays. Well, my family with me often on picnic on my holiday. Sometimes we go on picnic with friends in summer. Most of all I like when picnic is located near the river, where I can swim and fish. I really like fishing. But sometimes it is raining on a picnic. It is not a problem for my family. We always take a special tent, which we use for our picnic and hide from the rain.
I heard your school band won. It is great! What were you doing? How many bands participated? Who was in the group?
Anyway, I have to go now because I need to do my homework. Hope to hear from your soon.
Your friend,
Anna
The openings made in the process of extracting ore are called stopes. There are two steps involved in
stoping: development (preparing the ore blocks for mining) and production (stoping itself).
Technology has developed to the point where gold is now mined underground at depths of 40,000 m.
and the deepest surface mines have been excavated to more than 700 m.
It is the machines that provide the strength and trained miners who provide the brains needed today to prevail in this highly competitive industry.
Отверстия, сделанные в процессе добычи руды, называются забоями. Есть два этапа,
остановка: разработка (подготовка рудных блоков к добыче) и добыча (остановка).
