Study Of The Mine Water Inflow Prediction

The mine water inflow which is directly affect the production security of coalmine is one of the important index for evaluation of mine development economic andtechnological conditions. Accurate prediction of mine water inflow is of greatsignificance for water preventing and draining system s setting up and ensuring thesafety of coal production. Therefore, in this article by analyzing the differencesbetween the expected and actual water inflow, finding out the main control factors forthe error, which is the selection of calculation method, parameter and the applicabilityof parameters and calculation method. By studying the applicability of the existingformula of water inflow, comprehensive consideration water inflow forecast theory,and combining with the current frontier technology development, mine water inflowforecast evaluation system is putting forward based on fuzzy analytic hierarchyprocess. Firstly using the system to grade the perfect degree of the data collectingfrom mine of Kailuan Mining Area, and then according to the score obtaining theoptimal calculation method, this results is highly consistent with many algorithmoptimal results. The Kailuan Mining Area under different production system tunnel-working face-mining area-level mine water inflow forecast model and methodsystem has stronger practicability and guidance, greatly improved the precision ofmine water inflow forecast and has high application value in similar conditions.
