本文通过对河北峰峰四矿一个井田的水文补给边界条件、井田内的构造、放水试验的大青与奥灰水的水位动态资料等较全面而具体的分析,并和已有堵水工程进行了比较,得出了三点结论: 1.本区奥灰水垂直向上补给大青水; 2.岩溶水的不均一性,主要与垂直层面的张性裂隙构造有关,而且多集中分布在褶曲构造控制下岩层产状变化明显的局部隆起地段,尤其是陡缓突变的边缘地带; 3.垂向补给地段不仅位于大青与奥灰呈现对应位置关系的局部隆起地段,而且具有在不同情况下,大青与奥灰水位对应关系的水位动态特征。根据以上结论,对预测出的垂向补给地段进行注浆工程验证,结果使矿井涌水量减少达90％以上,仅排水电费一项,每年即可节约392万元,延长了矿井服务年限十年以上。
In this paper, a more comprehensive and specific analysis of the hydrological recharge boundary conditions, the structure within the minefield, the water level data of Daqing and Ordovician graywater discharge tests of a minefield in Fengfeng No.4 Mine in Hebei Province was carried out and compared with the existing water blockage project In comparison, three conclusions are reached: 1. Ordovician gray water supplies Daqingqing upwards vertically; 2. Inhomogeneity of karst water is mainly related to the vertical fissure structure, and more concentrated in the fold structure Under the control of the local rock formation obvious changes in the local uplift, especially the steep sudden changes in the edge of the zone; 3. Vertical recharge section is not only located in the green and the Ao gray showing the corresponding positional relationship between the local uplift, but also in different circumstances, Water Level Dynamic Characteristics Corresponding to Daqing and Aohui Water Level. Based on the above conclusions, the predicted vertical recharge section grouting project validation, the result of the mine water inflow reduced by more than 90%, only a drainage electricity, annual savings of 3.92 million yuan, extending the mine service life of 10 years the above.
