Abstract: With the expansion of the scale of mining and mining depth increasing year by year of Lvjiatuo mine,there are many security problems, such as stability of roadway and working face, and so on. In order to monitor the changing behave law of mine pressure and surrounding rock stress, eight borehole stress meters,five multi-point extensometers and three instrument of roadway are arranged respectively in the haulageway and bord-up.To monitor the stress of working face and deformation of tunel in the area, to make analysis of the results, to find behave law of mine pressure and forecast the behave law of surrounding rock in deep mining have important guiding significance for the mine safety production.
