Based on the synthetic optimization method with the theory of directed graph system simulation as the core, a method of system simulation and mathematical programming is combined to establish a computer aided design (SMCAD) system for opencast mine design and planning which is suitable for different burial conditions. Its functions cover the basic content of mining design decisions in surface mine design and allow for a series of comparative optimization of mining simulation calculations, optimization decisions and mining options. The system has realized the computerized, with multi-level menu, module structure, graphic display, dynamic tracking, interactive design and so on. The application shows that the SMCAD system has strong versatility and practicability, and the operation result is accurate and reliable.
