Predicting zones of increased water inflows in local folded structures

Purpose. To predict zones of increased water inflows based on geological exploration and mining-geological data in the real conditions an operating coal mine using method predictive evaluation prospects local structures for presence gas accumulations. Methodology. The research was carried out by constructing a map trend analysis. synclinal fold is allocated plan its main parameters – amplitude width are determined. Based these structure, authors performed calculations relative linear deformations volume deformation studied fold. Findings. According to deviation hyposometry layer (“Samarska” mine) from approximating surface, structure map. calculated volumetric rocks (siltstones sandstones) average values open porosity, fracture porosity absolute permeability were calculated. obtained indicate formation fractured zone with improved filtration capacity properties within area. actual mining data, defined area, there into workings, which further confirms results prediction. Originality. For first time, algorithm anticlinal accumulations used areas inflows. Practical values. In mine, area operations, predicting tested according folds
