Abstract: Mining-excavation relay plan is an important content in the production process of coal mine, it often need to adjust to adapt for the actual production of the mine. From the actual production, the study established the unit model for mining-excavation by GIS platform, and stored the data of mining-excavation by database. The study built a one-to-one correspondence between the mining figures and the mining grids, and realized the chart linkage, mutual generation and update of the mining figures and the mining grids. The study explores a rapid adjusting feasible method for mining-excavation relay plan.
