摘　　要：随着开采强度及深度的加大,单纯改造底板水层和薄层灰岩含水层的方法已无法满足减小突水系数的要求。目前比较成熟的方式就是采用地面区域治理注浆加固的方式,改变岩体水文地质条件,通过地面定向钻探施工工艺采用地面注浆的方式把相对含水层改造为相对隔水层。该方式可在实现矿井安全回采的同时,还保护了珍贵的地下水资源。With the increase of mining intensity and depth,the method of simply transforming the floor water layer and the thin-bed limestone aquifer can not meet the requirements of reducing the water inrush coefficient,and the current more mature is to adopt the way of grouting reinforcement in the ground area,change the hydrogeological conditions of the rock mass,and transform the relative aquifer into a relative aquifer by using the ground grouting method through the ground directional drilling construction technology,which can realize the safe mining of the mine at the same time,but also protect the precious groundwater resources.

关 键 词：突水系数 地面区域治理 注浆加固 含水层改造 安全回采
