为了探明鞍山式铁矿床深部賦有的富集铁矿和伴生組份,必須通过鑽探工程和穿透厚层而坚硬的貧鈇矿,才能达到预計的地質設計目的,因而对硬岩层鑽进提高效牢的技术探討,就占着重要地位,为了有計划的向硬岩关进軍,我們从如下几方面着手:①提高研磨材料的机械性能;②采用最优的技术参数和正确的操作规程;③采用多种几何形状的水口。 (一)研磨材料的选择通过金属学理論証明和鑽探工程实践需要,硬質合金是我們理想的研磨材料,而各类的硬質合金中以
In order to find out that the iron ore and associated components in the deep of Anshan-type iron deposit are enriched, it is necessary to go through the drilling project and penetrate the thick and hard lean ore to reach the predicted geological design purpose, To improve the technical efficiency of jail, it occupies an important position, in order to plan the hard rock off into the military, we proceed from the following aspects: ① improve the mechanical properties of abrasive materials; ② use the best technical parameters and the correct operating procedures ; ③ using a variety of geometric shapes of the nozzle. (A) the choice of abrasive material Metallurgical theory proved that drilling and engineering needs, carbide is our ideal abrasive material, and various types of cemented carbide to
