Abstract: In light of the characteristic of the spatio-temporal data of strip mining and based on the existing spatio-temporal data model, the object-oriented spatio-temporal data modeling was used to organize the spatio-temporal data of strip mining and make the strip mining scheduling by an arithmetic integrating dynamic programming and 0-1 integer programming. Taking He Shang Qiao Open-pit Mine of MaSteel as an example, a spatio-temporal database was setup to store the planning results. It was based on the spatio-temporal database with historical, present and planning data that the design and application development for the mining scheduling of strip mines were made.

Key words: Spatio-temporal data, block model, object-oriented spatio-temporal data model, mining scheduling for strip mines
