The physical rock breaking technology of thermal crushing overcomes the limitation of rock breaking by mechanical energy alone, does not produce dust and sparks, and greatly improves the working environment. However,fastest dth hammer, due to the problems of high energy consumption, high cost and serious wear and tear of props, it has not yet been popularized in China. At the same time, at this stage, China started late in the research and development of information technology and artificial intelligence technology, and the related core technologies of intellectualization are still mainly dependent on foreign countries. Therefore, at present, continuous mining has not been really realized in hard rock mines in China. 2. Transportation and lifting technology Transportation and lifting system plays an extremely important role in the production of underground mines. Through transportation and lifting, all links can be connected into an organic whole, so as to ensure the normal production of mines. The stope ore removal has experienced the development process of "manual, rail and trackless" transportation technology, and has formed a new situation from rail as the main and trackless as the supplement to trackless as the main and rail as the supplement. The key technologies of remote control are mainly embodied in three aspects: remote sensing of mining environment, remote operation of mining process and remote management and control of mining system, so as to realize the functions of automatic sensing and analysis, unmanned operation, remote allocation,dth hammer bit, automatic early warning and remote decision-making. Break through the key technology of intelligent mining of underground metal mines, improve the market competitiveness of mining enterprises and mining equipment manufacturing enterprises in China, and provide technical support for China to move from a big mining country to a powerful mining country.
