In view of the difficulty in collecting and sorting the parameter information of coal mine drilling equipment, combined with the requirements of drilling technology of drilling equipment, the functional framework, E-R model and database structure of drilling equipment parameter database are constructed. At the same time, with real-time optimization of drilling parameters, lithology identification and real-time browsing as the key contents, the multi-objective parameter optimization model, application of DMP monitoring, data mining and so on are designed The drilling parameter database system has the functions of multi tree data storage and data block adjustment. The experimental test and analysis show that the database system based on C / S structure works normally, and the performance improvement effect is obvious in the operation decision of drilling equipment and the identification of coal mine rock mass characteristics, which helps to improve the efficiency of drilling construction management and the intelligent level of drilling equipment.
