Abstract In order to improve the accuracy of the mine pressure appearance law, Huoshiju Mine set the surface of convergence, roof abscission layer anchor rope dynamometer, borehole stress meter and other mine pressure monitoring instrument in track transportation tunnel of 8714 working face. The technology collected a lot of pressure data, summarizes the mine pressure law in the track transportation tunnel of 8714 working face and got the corresponding conclusions, which provided a theoretical basis for roadway supporting design and optimization measures.
