蓝石棉是一种具有很好技术特性的特殊矿物。过去勘探蓝石棉矿床都以坑探作为主要手段，成本高，速度慢，对矿产破坏严重，为探索用钻探代替坑探多快好省地勘探蓝石棉的方法，我队近几年来进行了这方面的试验。钻探能否用于勘探兰石棉矿床，关键是取出满足地质要求的矿心，并能满足地质采样要求，也就是解决钻探矿心的代表性问题。我队通过反复摸索，基本上解决了蓝石棉取心问题。在此基础上，又提出了加密采样点用组合孔代替坑探的新任务。经过边生产、边试验，取得了大量的数据，证明组合孔可以代替坑探，作为勘探侏罗系似层状蓝石棉矿床的主要手段。目前这种方法已在我队生产中应用。
Blue asbestos is a special mineral with good technical properties. In the past, exploration of the Blue-Asbestos mineral deposit by pit exploration as the main means of high cost, slow, serious damage to the mineral, in order to explore the use of drilling instead of pounding faster and better way to explore blue asbestos, our team in recent years Aspects of the test. Whether drilling can be used for exploration of blue-asbestos deposits, the key is to remove the core to meet the geological requirements, and to meet the geological sampling requirements, that is, to solve the drilling of the representative representative of the problem. My team through repeated groping, basically solved the asbestos coring problem. On this basis, we propose a new task of using encrypted holes instead of pit. After the production side of the trial, obtained a lot of data to prove that the combination of holes can replace pit exploration, exploration of Jurassic stratiform blue asbestos deposit the main means. This method is currently used in my team’s production.
