| This paper systematically expounds the whole process of safety facilities design for large open-pit limestone mine based on the Wenzig East Limestone Mine of Gannan Qilian Mountain Cement Co., Ltd. On the basis of a full analysis of the geological conditions of the mine area, mining technology conditions and the main safety risks, the key links such as open-pit mining, slope stability, blasting safety, mine rock transportation, drainage system, power supply and, intelligent mine and safety management are designed for safety facilities in accordance with the current national laws and regulations and technical standards. The technical difficulties such as high slope stability analysis and monitoring safety countermeasures for road-shaft combined mining and transportation system, and blasting hazard control in complex conditions are studied emphatically. By adopting a series of advanced and facilities such as pre-fracture blasting, slope online monitoring, fully enclosed belt conveyor corridor, and automated control, a complete and reliable safety assurance system is constructed The design aims to control various safety risks in the mining process from the source, and provide technical support for the mine construction and safe production in the future 33 years, which has important reference value for the safety production design of similar mines. |
