Research on Water-Filling Patterns and Countermeasures

摘要

There are many water-filling factors in Xiaotun Coal Mine, such as effective precipitation, goaf wa- ter, mining-induced fissure zone, surface water system, aquifers and tectonics. For different mining levels, the relative importance of these factors is different, and the water-filling conditions is changed accordingly. So it is urgent to make it clear for mining. To ensure the safety of mining, we build a system of preventing mine water-filling using detailed AHP (analytical hierarchy process) calcula- tion. This system is based on the analysis of mine water-filling factors in order to define the relative importance of the factors. Decision-makers use it as a strong scientific basis for Xiaotun Coal Mine. The method offered in this paper has been proved to be very applicable.
