The Research Of The Open-pit' Economic Stripping Ratio And The Last Limit Depth

To determine open-pit limit is the important sector of its constructing and design. When open-pit limit is confirmed, the corresponding quantity of mine and rock can be confirmed. There are many complications that influent open-pit limit and the economic stripping ratio is the most important one. So the confirm of open-pit economic stripping ratio is very important. There are many techniques to confirm the economic stripping ratio inside and ~outside country at the present time, but there are no the last word. In this paper, the economic stripping ratio and the last limit depth were connected, to obtain the max profit we got the economic stripping ratio on the condition of optimal limit depth based on deferent deposit type and character. So the economic stripping ratio formula reflects the value and expenditure of ore on a certain extent. At last the open-pit last limit depth of the Lanjian-iron ore was optimized on this base applying this applied software.The author adopted mostly the software engineering to develop the system, and used the popular powerful system software as a tool .The Windows 98 is chosen as its operation platform, Visual Basic 6.0 , the object program system, as a tool, the unction of the system is realized more easily and naturally with the popular style of Windows. This system is rational in design, and stable and reliable in operation, and can meet the requirements of mine production and do very good for rational optimum production in mine enterprises. The results have shown that the method has remarkable effects and application prospects.
