Design and implementation of automatic continuous transportation system for shor-wall mining in coal mine

It is of great significance to adopt short-wall mechanized mining technology to improve the resource recovery rate and to solve the problems of underground coal pillar and irregular block mining, "three-under" coal mining, open-pit side pressing coal recovery, prolonging mine service life and so on.At present, the technical equipment of continuous shearer in China is developing rapidly, and the replacement of import has achieved good application results the lack of supporting continuous transportation system has been restricting the improvement of mine output and needs to be developed urgently Belt conveyor has the characteristics of long-distance continuous transportation, large capacity, high reliability, high performance-to-price ratio, and it is easy to realize automatic centralized control In order to improve the production capacity of the supporting transportation system behind the continuous shearer in the room and pillar mining technology of the coal mine, the importance of realizing the continuous transportation based on the long distance dynamic transportation and following the continuous shearer track is very important In this paper, the feasibility of automobile-train type continuous transportation system is discussed, and an automatic control algorithm for directly controlling the tracking operation of automobile-train continuous transportation system is put forward The key technical difficulties such as vehicle unit hinged mechanism and steering algorithm under different working conditions are studied The test results show that the application of vehicle train type belt continuous transportation system to realize automatic tracking driving can effectively solve the technical problem of realizing continuous transportation in room and pillar mining technology, realize continuous transportation system automatic driving, follow continuous shearer trajectory for accurate tracking control, and reduce operators It improves the driving flexibility and the ability to adapt to the environment.
