Application and Research on Positioning System of Fully Mechanized Mining Face Based on UWB Technology
The coal mining working face is the core area of coal mine production.It is extremely important to grasp the real-time working status of personnel and equipment in the mining area,and to detect and deal with equipment failures in the mining area early.Aiming at the 25041 fully mechanized mining face in Gaocheng Coal Mine only has a personnel positioning system(using wireless Wi-Fi positioning),which cannot achieve accurate positioning of coal machine equipment.In order to ensure the safe and efficient production of the mine,the positioning system of the 25041 fully mechanized mining face is conducted to be upgraded and transformed,a set of UWB based downhole fully mechanized mining face positioning system is proposed to achieve precise positioning of personnel and fully mechanized equipment in the fully mechanized mining face.The data is uploaded to the dispatch center to dynamically monitor the production status of the fully mechanized mining face.The on-site application shows that this UWB positioning system can achieve a three-dimensional positioning accuracy of 10-20 cm,effectively improving the management level of coal mine safety production.
