为研究煤层覆岩破坏应力及应变演化过程,设计出一套新的光纤光栅传感器布设工艺;以平庄煤矿为原型建立地质模型,利用该模型对采动过程中工作面前方矿压、位移进行监测。其监测结果、模型试验现象与工程实际相吻合,为工程实际中离层位置判别提供新方法。
In order to study the failure stress and strain evolution process of overburden strata, a new set of fiber grating sensor layout technology was designed. With Pingzhuang Coal Mine as the prototype, a geological model was established. By using this model, the strata pressure and displacement in front of mining face monitor. The monitoring results and model test phenomena are consistent with the engineering practice, which provides a new method for determining the position of delamination in engineering practice.
