摘要

Pit optimization is a tool to guide pit planning. They only give a raw model,actualy many of them give only a list of blocks, which parts can be mined profitably. The pit created by the optimizer does not contain haul roads, safety berms etc. These and many other design parameters must be taken into account in final planning of the pit. The pit optimizing methods can be divided into six groups by the algorithms used as follows: (1) Heuristic technques (coning); (2) Dynamic programming (Lerchs-Grossmann 2D); Linear programming; Network flow theory; Graph theory (Lerchns-Grossmann 3D, Zhao-Kim 3D); and New techniques (genetic algorithms etc.). The most used techniques are coning, as it is easily computerized and understood, and the Lerchs-Grossmann 3D algorithm, as it gives correct results. In this report, pit optimization is outlined to contain only the calculation of the limits of an ultimate pit.

7. Financial Development and the Distributional Effects of Monetary Policy Do the distributional consequences of monetary policy depend on the extent of financial development? Should optimal monetary policy vary across countries? In order to answer these questions, we develop a monetary growth production model with heterogeneous agents. In our economy, optimal policy needs to weigh the effects of policy across two groups — capital owners and individuals who hold liquid assets. While banks help limit the exposure to inflation, there are limits because money alleviates the frictions of private information and limited communication. In this environment, we compare two economies that are identical in every aspect except for their level of financial development. In a country with limited financial development, a stock market is absent. In the other, an equity market is active. In either economy, inflation adversely affects capital formation and output. Individuals who hold liquid assets are always adversely affected by inflation, but the attitude of capital owners depends on the level of financial development. In particular, in the presence of a stock market, the impact of inflation on the welfare of capital owners is non-monotonic. Nevertheless, optimal monetary policy is always more conservative at higher levels of financial development. [O] . TINA M. Edgar A. Ghossoub, TINA M. Robert R. Reedy 100
