Developmental prediction law of water-conducting fracture zones in shallow buried single coal seams.

Taking the mining of shallow buried coal seam 2 − 2 in Xiaobaodang coal mine as the background, the analysis methods of empirical formula calculation method, numerical simulation method, and algorithmic prediction method are comprehensively applied to study the influence of different mining heights, different working face lengths, and different mining depths on the development of water-conducting fissure zones in shallow buried coal seams. At the same time, the development of water-conducting fissure zone in Yushen mining area of northern Shaanxi Province is highly calculated and predicted by algorithmic model. The results of the study show that the PSO-SVR prediction model is more accurate and precise than the traditional empirical formulae and numerical simulations. The results of the study can provide a certain basis for water preservation mining in working face under similar geological conditions.
