- Abstract
- Open-pit mine design and long-term planning are crucial parts of the mining industry. It contains the technical plan that must be followed from the beginning of mine development to mine closure. Every deposit can be mined entirely, however, many things need to be carefully considered before mining the whole deposit. An optimal pit outline is one of the most important parameters that affect both the economy and the safety of mining. Therefore, the purpose of this study is to determine the effectiveness of an optimal pit outline by using both software and hand methods based on cost and revenue. This study investigates Dadiin-Khar Tolgoi2’s optimal pit outline and design to maximize the profit of using Surpac and Whittle software. The study compares the economic gain of both entirely extracted proved (B) and probable (C) reserve mines that were designed on the Surpac software and the hand technique of determining optimal pit outline. Whittle software computed that Pit Shell – 27 of Dadiin-Khar Tolgoi – 2 is the best pit outline regarding profit and safety. Besides, entirely mined Pit outline –B and Pit outline – C gives the loss in economics both
