众所周知,矿区封孔的目的在于防止或减少因钻探施工,给矿山开采、矿床保护以及地下水合理开发利用等方面带来之不良影响和危害。由于封孔工作本身就是钻探工程六项质量指标之一,它直接关系着勘探工作质量、速度、成本、消耗问题。因此,必须认真切实的做好矿床钻探的封孔工作。为供参考,现就封孔原则(包括应封的地段或部位)、封孔方法、封孔要求、封孔质量的检查分别阐述于后。
It is well-known that the purpose of sealing holes in mining areas is to prevent or reduce the adverse effects and harms caused by drilling construction, mining, deposit protection and rational exploitation of groundwater. As the sealing work itself is one of the six quality indicators of drilling engineering, it is directly related to the quality, speed, cost and consumption of exploration work. Therefore, it is necessary to conscientiously and effectively seal the hole in the ore drilling. For reference, is now on the principle of sealing (including should be sealed lots or parts), sealing method, sealing requirements, sealing quality inspection respectively described later.
