Abstract：In order to solve to many large equipments,complicated coal mining technics,an automation system of the fully-mechanized high cutting coal mining face was applied to improve a production automatic level and production efficiency.The paper stated control target and system composition of the automation system applied to the fully-mechanized high cutting coal mining face and in detail explained the composition and function of the surface monitoring and control system,network transmission system and site monitoring and control system. From a feed time of the coal shearer,smooth degree of the coal cutting,each pushing stroke of the powered support,each pushing time,ini-tial support force of the powered support,pushing forward effect of the scraper conveyor,system monitoring and measuring and others,a comparison and analysis were conduced on the application effect of the automation system applied to the No.8101 fully-mechanized high cutting coal mining face in Wangzhuang Mine.The results showed that the feed time was stable,coal cutting was smooth,in position rate of the powered support pushing forward was 92.8%,the powered support pushing time was improved with 29.2% higher than the manual pushing forward,the initial support force of the powered support was improved with 11.4%,the in position rate of the scraper conveyor was 100% and the results of the monitoring and measuring were good.
