Present situation and Development trend of Surface subsidence Monitoring and Prediction Technology in Coal seam Mining

The monitoring and prediction of surface subsidence in the coal mine is of great significance to the surface treatment and environmental protection of the coal mine. The monitoring and prediction methods of surface subsidence in the coal mine are described in detail, and the monitoring and prediction process of the coal mine are discussed and analyzed in detail. The problems existing in the monitoring and prediction of surface subsidence are pointed out. In the light of the existing problems, the future technology of the combined sensor based on the Internet and the combination of CCD and GPS is put forward, the monitoring data of the mining area is monitored in real time and the data processing is carried out, and the processed data is transmitted to the data center in real time. the data center adjusts the monitoring area in real time to achieve the optimal monitoring effect according to the monitoring results, and the future surface subsidence prediction and development should take into account the effects of the mining geological conditions, the mining process, the mining depth, the mining thickness and the like on the surface subsidence, The influence degree of the factors is determined in the prediction process, the prediction method is reasonably selected, and the prediction accuracy is improved.
