固体矿产绿色勘查钻探技术方法探索与实践

Exploration and practice of green exploration drilling technology methods for solid minerals

摘要:

西安矿产资源调查中心针对现有固体矿产地质调查（勘查）项目，积极探索和实践绿色地质勘查工作技术方法，因地制宜应用全液压履带钻机、便携式模块化钻机实施“一基多孔”，采用背包钻实施“以钻代槽”，通过优选环保型冲洗液，净化处理废弃冲洗液，控制临时占地规模等具体措施。与传统机场规格相比占地面积减少了80%~85%，临时便道修筑减少了60%~65%，工后复垦复绿达到了80%以上。通过绿色勘查成本费用分析，人员、临时用地（青苗）补偿、绿色环保材料及复垦复绿等费用成本总和降低了40%左右。最后探索实践了绿色勘查工作保障措施，对下一步绿色勘查工作提出了建议，为加强绿色勘查工作理念、完善相关的制度法规、激发绿色勘查工作活力提供了积极的导向。

Abstract:

Xi’an Mineral Resources Research Center actively explores and practices green geological exploration work technical methods for solid mineral geological survey（exploration） projects underway， and adopts specific measures such as applying full hydraulic crawler drilling rig and portable modular drilling rig to implement “ulti-holes from one site”， utilizing the backpack drill to implement “drilling instead of trenching” in accordance with local conditions， selecting environment-friendly drilling fluid， purifying and treating waste mud， and controlling temporary land occupation. Compared with the traditional drilling site size， the land footing area has been reduced by 80% to 85%， the construction of temporary access roads has been reduced by 60% to 65%， and the reclamation for farm land and green has reached more than 80%. Analysis of the cost of green exploration shows that the total cost of labour， the compensation for temporary land （green crop）， green environmental protection materials and restoration and greening has been reduced by about 40%. Finally， the support measures for green survey work are explored and practiced with suggestions put forward for the next step of green exploration work， which provides positive guidance for strengthening the concept of green exploration work， improving relevant systems and regulations， and stimulating the vitality of green exploration work.
