The Optimization of Drilling Water Inflow Prediction about the Underground Drain and the Study on the Attenuation Law of Water
Abstract: Taking QianYingZi coal mine 3212 working face of draining project as an example, specific to the important issue of “borehole water inflow forecast” during the present situation of coal mine safety production, based on the analysis and calculation of mine water inflow in different stages and conditions, we research the attenuation law of water inflow on the working face by analysing the accuracy on the calculation results of the inflow and the interference of the group of exploration boreholes inflow. Researches show that: the big well method is more reasonable than the original calculation method in process of the optimization to drain hole water in flow and it is more in line with groundwater movement rule. For multiple drilling exploration in the same drill socket, adjacent borehole of initial water has a tendency to decline. Give priority to those with static reserves of coal measures hole as a whole, it is on the decline.
