Digital Precision Design For a Platinum Gold Mine With Deep Ming in South Africa

Abstract

A platinum mine in South Africa is a deep mining mine that the mining design involves a series of difficult problems, such as high stress, high temperature and high lifting and so on. Choosing the right mining method and developing system is the key technology to solve these problems, and is also an important plan for mining design. First of all, based on multi index factors, 6 mining methods were quantitatively analyzed and scored, and the subleve open stoping method was chosen as the best mining method. In order to ensure the safety of this mining method, the hydraulic radius theory is introduced to analyze stope structural parameters stability. Secondly, with the view of global mining technology, we compared the development system of South Africa, China, Australia and other countries, and compared 6 development options in terms of technical, economic and security factors. The final selection of the development system combines the Chinese and Western design concepts, absorbs the advantages of each other and gets the recognition of the owners. Finally, we optimized the mining block, and carry out the 3D dynamic programming for the development system based on the 5Dplaner software, which realizes the digital precise design for the mine.
