鹤岗矿区煤层开采的主要充水水源为顶板白垩系石头庙子组砾岩裂隙水。由于含水层富水性不均一、矿区构造发育，煤层开采时，发生顶板突水的危险较大。“三图-双预测法”为评价煤层顶板突水危险性的主要方法之一。在该方法的应用中，如何选择适当因素建立含水层富水性分区图是方法的关键所在。以鹤岗矿区的新陆煤矿为例，通过对井田水文地质条件的分析，选择与石头庙子组砾岩裂隙含水层富水性密切相关的单位涌水量、含水层厚度、构造密度、物探解释的富水异常区等7个因素，应用层次分析方法，建立了“三图-双预测法”主要图件——煤层顶板充水含水层富水性分区图，为“三图-双预测法”评价顶板涌(突)水危险性奠定了基础。

The main water filling source during the coal mining in the Hegang mining area is roof Cretaceous Shitoumiaozi Formation conglomerate fissure water. Since inhomogeneous aquifer water yield property, developed mine area structures, can cause rather large roof water bursting hazard during coal seam extraction. The“three zoning maps plus two water inflow predictions”method is the one of major methods to assess coal roof water bursting hazard. In applications of the method, how to select appropriate factors to work out aquifer water yield property zoning map is the key of the method. The paper took the Xinlu coalmine, Hegang mining area as example, based on minefield hydrogeological condition analysis, selected 7 factors of specific capacity, aquifer thickness, structure density, and geophysical prospecting interpreted water yield property anomalous zone etc. closely related to Shitoumiaozi Formation conglomerate fissure aquifer water yield property, using analytic hierarchy process worked out the main map of the“three zoning maps plus two pre?dictions”method—the coal roof water filling aquifer water yield property zoning, thus has laid the groundwork for“three zoning maps plus two predictions”method to assess coal roof water inrush (bursting) hazard.
