| Summary: | Title screen The ground control using optical fibers is discussed. The designed monomode fiber pressure sensor is capable to perform high-precision measurement of overlying rock mass pressure imposed on walls of underground excavation. The mathematical apparatus is presented for the calculation of radiation intensity of optical wave traveling along an optical fiber with and with no mechanical effects. The simulation model is developed for an underground excavation with steel arch support. The model is equipped with the fiber-optic monitoring system and pressure sensors. This model enables practicing the ground control methods and measurements. The critical element of the simulation model is its hardware/software complex with interface showing four check zones with fiber-optic pressure sensors. This monitoring system is explosion-proof and is suitable for operation in super hazardous mines in terms of gas and dust outbursts. Режим доступа: по договору с организацией-держателем ресурса |
