The preliminary design of Copper Yu mine was completed in 1957, with a design scale of 400×104t/a. After the mine was simply put into operation in 1974, the production capacity was only (60 ~ 80) ×104t/a. In 1984, the natural caving mining technology was introduced from the United States, and the original adit - chute - auxiliary shaft development system was used to draw ore with electric rake. With the continuous development and advancement of science and technology in our country, the technical equipment in mining engineering keeps updating. At the same time, for the development of Shanxi North Copper Co., LTD., the company expanded the production scale of the second phase project to 900×104t/a on the basis of the original design in September 2019. The underground trackless equipment, as an important equipment for rock drilling, concrete support, shoveling, transportation and other work, can greatly improve production efficiency and expand production capacity. In this paper, the main characteristics and future development trend of underground trackless equipment are analyzed in detail, hoping to provide some suggestions for improving mining efficiency and safety.
