Taking a coal mine in Yushenfu as a case study, a 3D physical model (240 cm × 180 cm × 150 cm) was constructed and integrated with a distributed optical fiber sensing system. Optical Frequency Domain Reflectometry (OFDR) technology was employed to achieve high-precise monitoring of reservoir deformation. Concurrently, a numerical model was established in COMSOL Multiphysics to analyze the coupling between mine water diffusion and reservoir mechanics during reinjection, allowing comparison with the physical experiment. The results indicate that the physical model and numerical simulation have a good consistency. The OFDR technology effectively captured spatial disturbance caused by reinjection, with fiber strain curves delineating the extent and pathways of water migration. The reinjection process follows three stages: pore/fracture filling, hydraulic channel expansion, and sequestration pressure disturbance. OFDR strain monitoring exhibits excellent spatial resolution and measurement accuracy, making it highly suitable for physical modeling applications. Overall, this approach provides an effective means for evaluating the sequestration performance and optimizing the reinjection process in deep mine water reinjection systems.</div></div>","PeriodicalId":19663,"journal":{"name":"Optical Fiber Technology","volume":"95 ","pages":"Article 104399"},"PeriodicalIF":2.7,"publicationDate":"2025-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145097023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To verify the method, the parameter <em>D</em> is measured for a standard single-mode SMF-28 fiber with a length of 1.23 m. At a wavelength of 1550 nm, the value of <em>D</em> has been found to be approximately 16.6 ps/(nm∙km) with taking into account the DS. The root mean square error of measurements is 0.86 ps/(nm∙km). Another key feature of the method is that it enables accurate measurements of the parameter <em>D</em> across a broad spectral range in a relatively short time.

The output light intensities from the seven single-mode fibers (SMFs) of the fan-out are detected by photodiodes to quantify the optical power in each core of the SCF. Both simulation and experimental results verify a correlation between the light intensity distributions in the outer cores of the SCF and the rotational angle of the EDCF. Lorentzian fitting is applied to the intensity profiles of the six surrounding cores of the SCF at each angular position. By extracting the peak horizontal coordinates from these fittings, a linear relationship is established between these coordinates and the rotation angle.

For both methods, the CuNP/PVA film was coated with an index-matching gel sandwiched between two fiber ferrules. By incorporating CuNP/PVA-based SA in a laser cavity, stable Q-switched pulses were attained with a pump power range of 31–92 mW vs. 49–215 mW, a repetition rate (maximum pump power) of 16.61 kHz vs. 33.90 kHz, and a pulse width (maximum pump power) of 24.40 µs vs. 12.95 µs for CuNP/PVA-SMF-SA and CuNP/PVA-MMF-SA, respectively. The primary advantage of the CuNP/PVA-MMF-SA is its broader Q-switched pulse operation range relative to its counterpart, attributed to its weaker light confinement effect resulting from a bigger core diameter. This device could sustain a higher injected penetration power at 31.6 mW, yielding an energy pulse of 94 nJ, which represents a 1.57 enhancement factor.
