Water disaster law and prevention technology of Tangshan Mine based on statistical analysis

Mine water disaster is one of the geological disasters which seriously affect the safety production of coal mine. It is of great practical significance to analyze the occurrence regularity of mine water disaster for preventing water inrush accident and safe production. In this paper, the statistical analysis method is used to select the water disaster accidents occurred in the mining area of Tangshan Mine over the years, and combined with the mine hydrogeology and water filling conditions, the development law of water disaster is analyzed, and the time series, section and block, water source category, water channel and water inrush are deeply analyzed. The results show that the frequency of water inrush is decreasing. Water inrush points are mainly distributed in the middle of the well field. The main source of water is fissure water of sandstone in coal measure formation. The main water-conducting channel is water-conducting fissure; the water inrush is generally not large and the amount of water inrush soon attenuates Finally, combined with the actual mine production, a set of water prevention and control suggestions for Tangshan mine water disaster are put forward.
