Abstract: In order to solve the problems of long moving time and high safety risk of hydraulic support in fully mechanized mining face, this paper studies a new technology of hydraulic support loading and unloading device and moving group loader in fully mechanized mining face. And the industrial test was carried out on the No. 11105 fully mechanized mining face of Shanxi Youyu Dongwabei coal industry. The test results show that the loading and unloading device t achieves near loading and unloading hydraulic support, has stable performance, improves relocation efficiency, reduces the amount of floating coal work and damage to the bottom plate, improves the working environment, and reduces the labor intensity of the workers. It is safe and reliable to avoid roof caving and rope breaking and has remarkable economic benefit. It has great promotion value and broad market prospect.
