Research status and prospect of shearer positioning technology on fully mechanized coal mining face

Abstract

On the basis of development status of shearer positioning technology on fully mechanized coal mining face at home and abroad, characteristics of conventional shearer positioning technology, shearer positioning technology based on strapdown inertial navigation, shearer positioning error compensation technology based on strapdown inertial navigation, and shearer positioning technology based on combination of strapdown inertial navigation and other methods were analyzed. Development trends of shearer positioning technology were pointed out, which were researching positioning calculation strategy of strapdown inertial navigation, exploring tight coupling fusion strategy between wireless sensor network and strapdown inertial navigation, and studying shearer spatial positioning technology under complex vibration and multipath effect.
