Abstract：Exploitation of the deep coal is seriously threatened by water inrush from Ordovician limestone in North China type coalfield，so the coal mine safety production is directly related to the water-richness evaluation of Ordovician limestone aquifer. The water-richness of aquifer is evaluated by the units-inflow，which is the criteria according to regulations for mine water prevention and control. While the data are sparse in field exploration，the water-richness can not be evaluated comprehensively and objectively. In view of the above issue，the water-richness evaluation method based on grey correlation analysis，Fuzzy Delphi Analytic Hierarchy Process and geophysical exploration is proposed. Based on the background of Liangzhuang coal mine， the work of water-richness evaluation was carried out. Four major controlling factors were selected，including water inflow of drilling，the thickness of upper Majiagou Formation of Ordovician limestone aquifer，fault influencing factor and drilling flush fluid consumption. The total weights of all factors were obtained by the use of expert scoring method and grey correlation method. Following the above outlines，the mathematical model of water-richness index was established based on the method of grey correlation analysis and FDAHP. The data of geophysical exploration were collected to test the accuracy of the model and determine the partition thresholds. In addition，the results of water-richness index and geophysical exploration were used to evaluate the water-richness of Ordovician limestone. Furthermore，the validity and reliability of evaluate results were verified by engineering practices，including the data of water leakage of Ordovician limestone drills，Water inrush points，pumping tests and water source wells. In the absence of actual data of units-inflow，this study provides a way to evaluate the water-richness of Ordovician limestone aquifer.
