Introduction To date the development of truck monitoring dinpatch systems in the world, such as the DISPATCH monitoring system of the American Module Company has reached a highly mature level and is almost univernal. It has developed into a decisionmaking platform by management as a control system in multidirection al mining production, called Intellimine. In 1998, DISPATCH was introduced into the Dexing Copper Mine in Jiangxi, China. It has clearly enhanced the service efficiency of equipment, improved the management level in the open pits and obtained better overall benefits. In 2020, the Dandong Dongfang Measurement and Control Technology Co. Ltd.,together with the Qidashan Iron Mine have developed a dispatch management system for trucks in open pits. The system has bee indispensable to daily production management. It must be emphatically pointed out that the greatest disadvantage of these systems is that they cost too much. The major cause is that an independent munication work needs to be established and maintained by every open pit. Many mines can not afford such a system. However, using GIS/GPS/GPRS technologies, it is not necessary to establish independent munication works in every open pit. The work can be maintained and upgraded by a third party (., China Mobile Communication Co. Ltd). This can reduce costs considerably and provides a good platform for medium and small open pit mines to establish a fast, highly tive, and practical ground transportation system. Such a system is very important in enhancing labor productivity, reduce mining costs and promote mining technologies to an unprecedented level in open pits. 2 . GIS/GPS/GPRS GIS The Geographic Information System (GIS) is one kind of puter system gathering, storing, managing,analyzing, demonstrating and applying geographic information. It is a general technology that can analyze and process enormous amounts of geographic data. It takes a geographic space database as its foundat ion, uses a geographic model analysis method to provide many kinds of spatial and dynamic geographic information and serves as a geographic research and decisionmaking tool. It has some basic functions such as ele
