Research on Key Technologies of Intelligent Collaboration for Comprehensive Mining in Underground Coal Mines
To improve the intelligent level of coal mine comprehensive mining and solve the problems of precise positioning and motion coordination control of comprehensive mining equipment under complex underground conditions,research on intelligent coordination technology of comprehensive mining is carried out.Build an intelligent collaborative overall architecture scheme,with a focus on real-time positioning and motion collaborative control of comprehensive mining equipment based on laser sensing,prediction and verification of cutting trajectory of coal mining machines.The results show that the laser positioning system of the underground comprehensive mining equipment has a continuous and stable high-precision positioning function,with an accuracy of up to 20 mm level.Through the precise correlation between the comprehensive mining equipment and the position of the coal seam,the adaptive adjustment and control of the shearer drum cutting basically reach the level of anthropomorphic cutting.
