Abstract：The production requirements for the fully mechanized mining face are"three straight,two flat,and two unobstructed",where"three straight"refers to the straight coal wall,straight scraper conveyor,and straight hydraulic support.A positioning method of"Inertial Navigation+Odometry"combined navigation was proposed to solve the problem of poor straightening accuracy caused by high manual intervention rate,slow straightening speed,and low inertial navigation accuracy in the current scraper conveyor straightening process.Combining with a two-step error correction algorithm,the precise positioning of the coal machinery on the working face was achieved.Furthermore,by using the method of pulling straight lines at both ends,a scraper conveyor and hydraulic support straightening strategy based on straightening at both ends was proposed,and an automatic straightening system for the working face was designed.And through testing in the fully mechanized mining face of Ningmei Jinfeng Coal Mine,the effectiveness of the straightening strategy was verified,meeting the requirements of automatic straightening of the working face.
