Mine mining plan preparation is an important work in the production management of mining enterprises. The traditional manual preparation of mining plan is not well adapted to the increasingly complex coal mine production environment, which leads to problems such as tight mining succession. Therefore, a mine mining plan control system is designed based on dynamic inference. This system adopts the dynamic planning method, according to the characteristics and requirements of mining production, establishes a dynamic deduction model, calculates the appropriate production cycle and the amount of coal to be mined in each quarter, and realizes the dynamic deduction of the mining process with the help of the database model of GIS and software such as AutoCAD. In order to cope with the situation that the production plan can not be completed on time, by setting up the outline level and setting the connection relationship between different tasks, the problem of tense mining succession is effectively avoided, and optimization calculations are realized with the help of computers to achieve the dynamic regulation of the mine mining plan.
