Stone coal machine company's two scientific research achievements have reached the international advanced level

Recently, two new product research results of the EBH300(A) rock tunneling machine and special-shaped rail track transportation equipment developed by Jizhong Energy Shijiazhuang Coal Mining Machinery Co., Ltd. passed the expert appraisal, and the project has reached the international advanced level.
The EBH300 (A) cantilever type rock tunneling machine developed by Shimite Co., Ltd. was the first to adopt advanced technologies such as computer intelligent control, two-variable hydraulic system and reverse oil filling of the oil cylinder. The high degree of automation of the whole machine ensured the requirement of cutting hard rock. , It can effectively reduce the labor intensity of workers and improve the forming quality of rock roadway and the tunneling speed. The cross section design of SMJ160 special-shaped rail rail transport equipment jointly developed by Shimeiji and Fengfeng Group is scientific and reasonable, and the vehicle system can effectively track rails all the way. The operation has a large braking force and is safe and reliable, which effectively improves the safety level of rail transportation in coal mines and enables efficient operation without reloading. The project has reached the international advanced level, in which the shaped rail and its braking method have reached the international advanced level.
Experts from the China Coal Society, China University of Mining, Shandong, Shanxi, Henan, Hebei and other places believe that the scientific achievements of the two new products have reached the international advanced level, with significant social and economic benefits, and have broad prospects for promotion and application.
