The electro-hydraulic control technology of hydraulic support, which is the main equipment of fully mechanized coal mining face, is an important symbol in coal mine for achieving efficient exploitation.It is very important to increase the automatic level of hydraulic support to improve production efficiency and ensure the safety of work face.The birthplace of the electrohydraulic control technology is Britain.The technology was developed in Germany, gradually extended to the world and became mature in 1990 s.But the study of the electro-hydraulic control technology in our country started relatively late.Although the basic function of domestic products has caught up with the world's advanced level, but the reliability, stability and intelligence are still necessary to improve.Based on the analysis of the necessity of the development of electro-hydraulic control technology, this paper reviews the functional requirements and technical characteristics of the electro-hydraulic control technology at different stages of development, introduces the current research of the electro-hydraulic control technology at home and abroad, and prospects the development direction of the hydraulic control technology of hydraulic support in fully mechanized mining face.
