Abstract: Taking Mengku Iron Mine of Xinjiang Bayi Iron & Steel Co.as a specific case，and in combination with the development of ASAD application technology，the paper describes the conception of the compilation of geological，measurement and mining system software for open pit mines and the key techniques for its realization.It is summarized that mine digitalization development is a process that involves many aspects such technology，personnel and mine management，which are all embodied in the personalized characteristics of the system software.This system software has been developed and applied for many years and is being continuously improved and updated so as to fully satisfy the requirement of mine personalization and to better serve the auxiliary design and management of open pit mining production.

Key words: Mine geological, measurement and mining system software, Auxiliary design and management of open pit mining production, ACAD's secondary development and application
