我队的前身,是从事钼矿钻探的地质队。七九年接受了洛南黄龙铺钼(铼)矿床钻探深部评价的任务。该矿区位于陕西东秦岭华山地区,先后有三个地质队进行钻探施工,钻探工程质量低劣,不能满足地质要求。为满足矿层任截4米(81年部规定10米)采取率不低于75%的要求和保证顺利施工,我们在取心工具,护壁方法、钻探工艺、操作技术,管理制度等方面作了一些工作,收到了一定的效果。 My team’s predecessor, is engaged in molybdenum drilling geological team. In 1979, he accepted the mission of drilling deep evaluation of the Luonan-Huanglongpu molybdenum (rhenium) deposit. The mine is located in the Huashan area of ​​East Qinling, Shaanxi Province. Three geological teams successively conducted drilling and construction. The quality of the drilling works was poor and the geology requirements could not be met. In order to meet the requirement of taking the mining area 4m (81m prescribed 10m) and adopting the requirement of not less than 75% and ensuring the smooth construction, we have made some suggestions on coring tools, wall protection methods, drilling technology, operation technology and management system Some work, received a certain effect.
