It w s concluded through the site survey nd n lysis th t the Ch mb ishis m ining dyn m ic pressure w s vertic l one nd concentr ted on bedding nd joint- developed orebod ies nd surrounding rock, thus le d ing to gre t m ount of c ving of l new ys nd stopes. In view of th is, the m ine dopted depressurized m in ing nd bolting support, wh ich effectively controlled the ground pressure, mi proved the utiliz tion r te of prep r tion engineering nd sm oothly re lized s fe, efficient nd econom ic ex tr ction of orebodies.
