“…As shown in Figure 2, because the position and attitude of the shearer are three-dimensional, the IMU of the shearer positioning system is not a single-axis gyroscope and an accelerometer, but a three-axis gyroscope and a three-axis accelerometer, whose axes are orthogonal. Shearer positioning entails actually determining the coordinates of the shearer relative to a certain reference coordinate system at a certain time [33]. However, the angular velocity and acceleration measured by the shearer positioning system are in the carrier coordinate system and cannot be directly used for the calculation of the position and attitude of the shearer.…”

Automation and intelligent coal mining comprise the most important fields in coal mining technology research. The key to automation and intelligent coal mining is the automated mining of the working face, and accurate positioning of the shearer is one of the most important technologies in the automated mining process. However, significant defects in non-inertial navigation system (INS)-based methods have led to low positioning accuracy. In this paper, we propose a new shearer positioning technology to further improve the positioning accuracy of the shearer and monitor the shearer position in real time. The shearer positioning system proposed is based on the strapdown inertial navigation system (SINS). We conducted shearer positioning experiments with gyroscopes, accelerometers, and other inertial navigation instruments. The experimental results are thoroughly studied on the basis of error compensation techniques such as inertial instrument zero bias compensation and Kalman filter compensation. Compared with traditional shearer positioning technology, the experimental results show that the shearer positioning system based on SINS can achieve more accurate positioning of the shearer and can accurately reflect the running characteristics of the shearer working the mining face.
