Abstract: Jinchuan No.2 mine area is an extra large underground mine in China.The underhand drift cemented cut and fill stoping with mechanized panel is adopted.The Jinchuan No.2 mine has large continuous exploit area and large annual output of ore. Additively，due to the relatively poor engineering geological conditions，large stress and other reasons，the ground pressure problem becomes more serious. This paper introduces the basic pressure monitoring program in No.2 Mine Area，the arrangement of the measuring point and its typical layout，monitoring methods and equipment etc.; Based on the existing monitoring data of rock mass stress and displacement，the data varies and its trends of the monitoring points are analyzed preliminarily. During the exploitation process of large mining area and level pillars，the influence to the rocks at Line No.14 air shaft and wide range of upper and lower panel are analyzed and evaluated，obtaining some achievements which play some guidance and reference value in safety production.

Key words: Bulky filling, Level pillars, Ground pressure monitoring, Mining influence
