矿用采动应力监测传感器的比较和应用
Comparison and Application of Mining Stress Monitoring Sensor
【摘要】 应力和应变测量已广泛应用于地应力测量中,其采动应力监测则是一种典型的相对地应力测量。重点分析了两种典型的采动应力监测仪器,即钻孔应力计和空心包体式钻孔三向应变计的技术特点,以及在采动应力监测中的优缺点。
【Abstract】 Sress and strain measurement are widely used in situ stress measurement,and mining stress monitoring is a typical relative stress measurement.Analyzes the technique features,advantanges and disadvantages between borehole stress meter and hollow inclusion triaxial strain cell in minging stress monitoring.
