甘豪矿井下火药库,因设计位置不当,使主库房正处在较复杂的水文地质条件中,南北有两条断层斜交通过。因受断层错动,使主库房接近砂岩含水层,在主体工程完工后,因涌水和淋水面积过大,不能交付使用。矿井定为84年12月移交生产,工期紧迫,为保持火药库的干燥又能按期投产,我们对主库房淋水地段,采取注、堵和疏导的治水方法,取得了良好的效果,从而避免了火药库搬换位置的浪费,其施工方法简介如下:
Ganhu underground mine powder library, due to improper design of the location, so that the main reservoir is in more complex hydrogeological conditions, north-south two cross-section through the fault. Due to fault dislocations, the main cofferdam is close to the sandstone aquifer. After the main project is completed, it can not be delivered due to the gushing and sprinkling area is too large. The mine was scheduled to be handed over to production in December, 84. Due to the tight deadline, in order to maintain the dryness of the powder repositories and put into operation on schedule, we have taken good measures to prevent, The gunpowder warehouse to change the location of the waste, the construction method is as follows:
