از آنجا که در معادله خط راست، ضریب x شیب خط هست، پس شیب در معادله فوق برابر ۲ است. اگر بخواهیم یک خط دیگر عمود بر آن پیدا کنیم شیب آن باید معکوس و قرینه این معادله باشد یعنی m = − 1 2 m=-frac{1}{2} m = − 2 1 .
The Oyu Tolgoi cluster of seven porphyry Cu-Au-Mo deposits in southern Mongolia, define a narrow, linear, 12 km long, almost continuously mineralised trend, which contains in excess of 42 Mt of Cu ...
The Oyu Tolgoi copper mine in Mongolia is a world-class open pit mine and underground project. More than 80% of Oyu Tolgoi's total value lies deep underground. We are building an underground mine complex, that will use block-caving mining techniques to extract the ore and transport it to the surface.
MELBOURNE, Australia--(BUSINESS WIRE)-- Oyu Tolgoi LLC has completed an updated feasibility study (OTFS20) and is in the process of submitting this to the Government of Mongolia. The OTFS20 has been prepared in accordance with Mongolian regulations and standards which require mining companies to submit updated feasibility studies every five years.
