Precise Shearer Positioning Technology Using Shearer Motion Constraint and Magnetometer Aided SINS [PDF]
Mathematical Problems in Engineering, 2021 The key technology to realize intelligent unmanned coal mining is the strapdown inertial navigation system (SINS); however, the gradual increase of cumulative error during the working process needs to be solved. On the basis of an SINS/odometer (OD)-integrated navigation system, this paper adds magnetometer (MAG)-aided positioning and proposes an SINS ...

A LiDAR-Aided Inertial Positioning Approach for a Longwall Shearer in Underground Coal Mining [PDF]
Mathematical Problems in Engineering, 2021 The absolute three-dimensional position of a longwall shearer is fundamental to longwall mining automation. The positioning of the longwall shearer is usually realized by the inertial navigation system (INS) and odometer (OD). However, the position accuracy of this positioning approach gradually decreases over time due to the gyro drift.
