Detection method for preventing coal piling on fully mechanized coal mining face

Abstract

The invention discloses a detection method for preventing coal piling on a fully mechanized coal mining face. The detection method comprises the following steps: S1, load grading: dividing load conditions into a no-load condition, a light load condition, a medium load condition and a heavy load condition; s2, acquiring stable current data of the scraper conveyer under different load grades; s3, determining a current value interval of each load level by using the load levels and the current data; s4, determining the load grade of the current coal pile according to the current data acquired in real time; s5, according to the load condition, whether coal piling occurs or not is judged, and early warning is sent; and S6, dynamically generating guidance parameters for adjusting the running state of the equipment. According to the invention, the load state of the fully mechanized coal mining face is judged according to the current value of the scraper conveyer in the coal transportation process, and the guidance parameters for adjusting the operation state of the equipment are dynamically generated through different load states, so that the detection method is simple and reliable, and coal piling can be effectively prevented.
