| 摘 要： | 随着吕家坨井工矿开采规模的扩大和开采深度的逐年增加,面临着诸如巷道和工作面稳定性等安全问题,为了监测采场周围岩体和煤体应力的变化规律,分别在采面机巷和上山中布置8个钻孔应力计5个多点位移计和3组断面收敛计对区域内采煤工作面和巷道进行现场应力和变形监测,并对结果做出分析,找出矿压规律,对深部开采围岩矿压规律进行预测,对矿山安全生产具有重要指导意义。

| 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. |

| Keywords: | detection deep mining deformation of surrounding rock abutment pressure |
