绿色勘查技术在河北省古马铁矿钻探工程中的应用

Application of green deep exploration drilling in Guma Iron Mine in Hebei province

随着矿产资源勘查工作量的加大,勘查与环境矛盾不断出现。深孔钻探施工周期长,对施工场地地表土壤及植被污染严重;机械设备修理、废弃油料、存放油类的临时仓库、废弃泥浆、岩粉如处置不当也会对地表土壤产生污染;钻孔冲洗液漏失会污染地下水等。因此,采取针对性的技术措施防止破坏、污染生态环境,在当前矿产勘查钻探施工中至关重要。本文针对河北省滦州市古马铁矿深部钻探工程项目,在施工前、施工中、施工结束采取了铁质循环槽、铁质水箱、防渗布和面包砖硬化地面等一系列绿色勘查技术措施,确保了钻探施工场地未受污染,施工结束后恢复原地貌情况良好,为以后岩心钻探工程中深孔绿色施工提供了可借鉴的经验。

With the increase of exploration drilling works,the conflict between exploration drilling and conservancy deepens,such as pollution of topsoil and vegetation due to long drilling periods of deep holes,improper disposal of drilling mud and cuttings,etc.On the deep drilling project of Guma Iron Mine in Luanzhou city,Hebei province,a series of green exploration technical measures,such as iron circulating tank,iron water tank,impervious cloth,bread brick hardened ground,were taken before and during drilling operations,so as to ensure that the drilling site is not polluted and the original appearance is reinstated after drilling.The experience can be used for reference for green drilling of deep core holes in the future.
