Abstract:

The prediction height of water-flowing in fractured zone of overburden strata is the difficulty of research. A deep learning model is proposed to estimate the height of the water-conducting fracture zone based on simulation experiments of fiber-optic monitoring overlying rock deformation. The key factors， such as the frequency shift value of the optical fiber sensor， the height of the sensor， the advance length of the working face， the lithology and structure of the overlying rock were select in this model. Firstly， the frequency shift value is decomposed into three components， random frequency shift value， periodic frequency shift value and trend frequency shift value. Then， deep learning model are built to predict each component， and prediction component are superimposed to form the frequency shift value of sensor. Finally， the development height of the water-conducting fracture zone is inferred in accordance with the relationship between curve of frequency shift value change and the development height of fracture zone. The experiments show that the average estimation error of such height is about 11 mm. The predicted heights are accurate and reliable， which can also meet requirements of an engineering test practice.

Key words: smart mining, ensemble empirical mode decomposition, hybrid deep learning network, height of water-flowing fractured zone, prediction of frequency shift value of optical fiber sensor
