摘要
钻探是矿山地质环境调查工作中获取地层信息的一种重要手段,钻探质量直接影响着调查工作的质量。在北京市矿山地质环境调查过程中,基于矿区取样质量要求,通过对比部分钻探取样设备和技术的优缺点及适用性,选择将直推钻探技术应用到矿山地质环境调查取样工作中。在取样过程中,Geoprobe-7822DT直推式土壤钻机配备了DT22和MC5直推钻具进行钻探取样,2种直推钻具发挥了各自的优势,提升了矿山地质环境调查取样工作的质量和效率。MC5直推钻具适用地层范围更广,更加适用于矿区深部土壤钻探取样。
Drilling is an important means for obtaining stratigraphic information in mine geological environment investigation.The quality of drilling directly affects the quality of investigation.In the process of mine geological environment investigation in Beijing,based on the quality requirements for sampling of the working area in the mining area,through comparing the advantages,disadvantages and applicability of some drilling sampling equipment and technologies,this paper applies direct push drilling technology to the sampling work of mine geological environment investigation.During the sampling process,the Geoprobe-7822DT direct push soil drill is equipped with two types of direct push drilling tools including DT22 and MC5 for drilling and sampling.Both types of direct push drilling tools have their respective advantages,which improve the quality and efficiency of the sampling work of mine geological environment investigation.But the MC5 direct push drilling tool,better at deep soil drilling sampling,is more suitable for the stratum of the working area in the mining area.
