Since the 1960s, mining science and technology in China has experienced two technical innovations, i.e. the “Masonry Beam Theory (MBT)” and “Transfer Rock Beam Theory (TRBT)”. Based on those theories, the conventional mining method (being called the 121 mining method) was established, consisting of...
