利用新型两用多点位移计测算围岩深部位移的方法研究

Method to Measure and Calculate Deep Displacement of Surrounding Rock Based on New Dual Multi Point Gauge

阐述了巷道围岩深部及表面位移的测量原理,提出了一体化测量巷道围岩深表位移的两用多点位移计,并应用于淮南潘一东矿沿空留巷支护设计中,与传统测量手段进行对比,其避免了因不同点处围岩位移不同步及受钻孔影响导致测量错误的现象。工程应用表明,其所测数据能够真实确定深部围岩零位移点,为支护设计提供重要参考。

The paper stated the measuring principle of the deep and surface displacement of the surrounding rock along the mine roadway, a dual multi point displacement gauge was provided to the integrated measurement of the deep surface displacement of the mine roadway surrounding rock and to apply the design of the support of the gateway retained along the goaf in Panyi East Mine of Huainan. In comparison with the conventional measuring means, a nonsynchronous displacement of the surrounding rock at different location and the measuring mistakes affected by the borehole could be eliminated. The engineering application showed that the data measured could accurately determine a zero displacement point of the deep surrounding rock, could provide important references of the support design.
