Xinhua News Agency, May 15 - The 10th issue of the "Qiushi" magazine published an important article by General Secretary Xi Jinping titled "Correctly Understanding and Grasping Major Theoretical and Practical Issues in Our Country's Development." The article points out the need to correctly understand and grasp the supply guarantee of primary products. Firstly, enhance the domestic resource production guarantee capability. Increase exploration efforts, implement a new round of strategic actions for mineral discovery breakthroughs, and improve the development and protection level of marine and mineral resources. Secondly, leverage the supporting role of state-owned enterprises to accelerate the development and application of advanced extraction technologies for resources such as oil and gas. Thirdly, strengthen the construction of the national strategic material reserve system. Fourthly, optimize overseas resource guarantee capabilities, effectively preventing...

Hollow steel materials are used to produce drill rods: electric furnace smelting - LF furnace refining - large billet continuous casting machine casting.

There are over 200 models of hydraulic rock drills produced by companies such as Anbai Tuo, Sandvik, Montebet, Japan's Furukawa, and Finland's Doof, along with continuous product modifications, which should result in more than 400-500 types of drill bits.

According to a report by Mining.com, the Fraser Institute in Canada has released its latest annual survey report on mining companies, stating that resource-rich Western Australia has replaced Nevada in the United States as the best destination for global mining investment.

The drill rod is an important accessory of the rock drill and a key component of the drilling tool assembly. The drill rod cannot be used independently; it needs to be paired with a rock drill for application on drilling equipment. Drilling equipment is generally used for tunneling in underground mines.
