Multi-Index Monitoring and Evaluation on Rock Burst in Yangcheng Mine

Monitoring Subsidence Area in Mine Based on Multi-source and Multi-temporal Remote Sensing Data

In this paper, the decision-making information of subsidence area for twenty years is extracted, using Landsat multi-band and multitemporal remote sensing data, SPOT 5 texture features, DEM elevation, the methods of data fusion and principal component analysis and GIS technology, thereby the spatial and temporal distribution of change of subsidence area in mining is acquired from years 1987 to ...

Forecasting Rock Burst in Coal Mines Based on Neural Network

In view of disasters caused by rock burst becoming more and more serious in coal mine production, three models are established for evaluation and prediction the rock burst risk based on artificial neural network. First, ten indicators are determined which have a larger influence on rock burst. Then two back propagation network models are trained using the original data and the processed data re...

Mine Subsidence Monitoring Using Multi-source Satellite SAR Images

Ground subsidence due to underground mining has posed a constant threat to the safety of surface infrastructure such as motorways, railways, power lines, and telecommunications cables. Traditional monitoring techniques like using levels, total stations and GPS can only measure on a point-by-point basis and hence are costly and time-consuming. Differential interferometric synthetic aperture rada...
