Background
With the rapid development of the production and construction of open pit coal mines in China, the coal pressing amount of the open pit coal mine has reached 5 hundred million tons, and if safe and efficient mining cannot be realized by a large amount of open pit coal pressing resources, great resource waste and environmental damage are caused. The open pit coal mine side mining technology is used for mining side coal pressing resources to the maximum extent on the premise of minimally damaging earth surface rock and soil coverage and ground vegetation, does not basically cause adverse effects on the environment and other resources, and can obtain good economic benefits.
For the open pit coal mine side coal pressing and residual coal mining technology, the technology development of developed countries in Europe and America is earlier and more mature. The side mining of the open pit coal mine mainly comprises a spiral drilling machine mining method, a side coal mining machine mining method and a continuous coal mining machine side mining method. In the beginning of the last 40 th century, the major coal producing countries in Europe and America utilize a spiral drilling machine to recover open slope coal pressing resources, utilize a screw drill to drill into a slope, and export coal by a spiral line. The side coal mining machine for mining open-pit slope coal pressing and outcrop coal is formally provided by the SHM company in 1994, the equipment integrates the functions of mining, transportation, monitoring and the like, and support and a large amount of mine construction are not needed in mining. Currently, more than 50 of the devices are put into production in the United states, Russia and other countries. In 1997, BHP Union Inc adopts a long-term 12CMl2B continuous miner to regularly excavate a coal roadway designed on a side slope with a multi-section lap belt conveyor, a control platform of the miner is placed outside the excavated coal roadway close to a side slope coal pressing wall, and the mining system achieves good use performance abroad. However, the cost of the foreign complete set of highwall mining equipment is high, and the equipment is difficult to completely adapt to the geological conditions of the coal field and the production organization of the strip mine in China during the use process, so that the equipment is limited to be used in the highwall pressing coal mining of the strip mine in China.

Shanxi Tiandi coal mining machine equipment Limited company cooperates with the inner Mongolian Wulan coal mine, and utilizes a domestic continuous coal mining machine matched with a multi-section lap belt transfer conveyor to carry out slope coal pressing mining, thereby proving the feasibility of the continuous coal mining machine in the slope mining.
The system takes the traction of a continuous miner as the only walking power, the mining depth is limited, and the extraction rate of the slope coal pressing resource is low; the equipment has no self-rescue capability, and personnel need to enter a non-support roadway to repair the equipment, so that the safety is poor; the belt reversed loader is difficult to assemble and disassemble, the labor intensity of personnel is high, and the width reservation of a step flat disc is large when the whole machine moves forward and backward; the dust in the tunnel is directly discharged to the atmosphere through the dust removal air duct, and the dust pollution on the mining site is serious; the system adopts laser pointing, has no navigation function, and cannot accurately ensure the safety width of the reserved coal pillar in the middle after the mining depth is gradually increased.
