Dear Distinguished Visitors and Friends,
Welcome to the official website of Luoyang Jiujiu Technology Co., Ltd. (Jiujiu Tech)! Whether you are seeking a reliable partner for rock breaking equipment in major infrastructure projects or exploring innovations in rock breaking technology, we are truly honored by your visit.
Amidst the vigorous wave of global infrastructure development, the efficient advancement of tunnels, rail transit, water conservancy hubs, and other major projects relies heavily on high-quality rock breaking equipment. Having specialized in this field for nearly three decades, Jiujiu Tech, as a National High-Tech Enterprise, has always been rooted in technology, committed to quality, and dedicated to service. With profound industry expertise and mature international cooperation experience, we have provided reliable rock breaking solutions for numerous significant projects worldwide. Here, we sincerely present the four core reasons to choose Jiujiu Tech, hoping to build deeper trust and collaboration with you.
1. National-Level Technical Endorsement for Assured Quality
Our technical strength stems from long-term, in-depth participation in national key scientific research initiatives—from the National "Seventh Five-Year Plan" R&D on wear-resistant materials and TBM/Shield Machine National Science & Technology Projects to key programs like the "863 Program". We have also undertaken the SME Innovation Fund project for shield machine cutters and the National Torch Program project, and participated in formulating several national industry standards such as "Rock-breaking rolling cutter" and "Building construction machinery and equipment-Direct/reverse circulation drilling rig". Relying on the Henan Provincial Shield Machine Cutter Engineering Technology Center, our professional R&D team holds 85 intellectual property rights. Our core patents significantly enhance cutter wear resistance and service life, successfully solving complex geological construction challenges. Furthermore, the company holds international authoritative certifications like GB/T19001-2016/ISO9001:2015, ensuring our product quality fully complies with mainstream global engineering standards.
2. Comprehensive Product Portfolio for Precise Matching to Diverse Needs
We have built a complete range of rock breaking equipment systems, covering core products like Shield Machine/TBM Cutters, Engineering Drill Roller Cutters, Raise Boring Machines, and wear-resistant/heat-resistant components. Our 12-19 inch roller cutters are fully compatible with international mainstream tunnel boring machines (e.g., Herrenknecht) for seamless interchangeability without requiring modifications. For specific challenging conditions like large-particle cobble layers or hard rock formations, we offer end-to-end customized services from solution design and product development to manufacturing, helping enhance construction efficiency and reduce overall costs. With sufficient production capacity, we can annually manufacture 30,000 sets of rock breaking tools and 10,000 tons of wear-resistant/heat-resistant parts, ensuring stable bulk supply for various projects.
3. Mature International Service, Providing Global Support
Over the years, our products have been exported to numerous countries and regions across Europe, America, Southeast Asia, etc., successfully serving many major overseas infrastructure projects and earning widespread recognition from international clients. To better serve global visitors, we have established a professional international business team proficient in cross-border trade rules and multilingual communication, offering full-chain services including pre-sales technical consultation, in-sales installation guidance, and after-sales maintenance. Concurrently, we have optimized our global logistics and warehouse layout to effectively shorten delivery cycles, ensuring timely product arrival at project sites, and can flexibly adapt to different national technical standards, providing comprehensive support for project smooth progression.
4. Solid Operational Strength for Win-Win Long-Term Development
As an NEEQ-listed enterprise, we maintain standardized corporate governance structure and steady operational performance. In 2024, the company achieved an operating income of RMB 124 million with steadily growing net profit, demonstrating strong market competitiveness and development resilience. We consistently adhere to the philosophy of "Customer First, Quality Foremost, Integrity-Based, and Collaborative Synergy". We not only strictly control product quality but also strive to build long-term, stable, and mutually beneficial relationships with our partners. Moving forward, we will continue to deepen technological innovation, optimize our global service network, and contribute to high-quality global infrastructure development with superior products and services.
Your attention is the driving force behind our progress. Should you wish to learn more about our products, discuss customized solutions, or have any inquiries, please feel free to contact the International Business Department via the website message system, phone, or email. Our professional team will respond promptly to your needs and provide personalized one-on-one service.
We look forward to joining hands with you to embrace new opportunities in global infrastructure development and build a high-quality engineering future together!
Best Regards,
Luoyang Jiujiu Technology Co., Ltd.

Development Status of Large-Diameter Drilling at Home and Abroad
Abstract: Large-diameter drilling (also known as shaft sinking by drilling method) originated in Western Europe. After technological iterations in various countries, it has been widely applied and relevant equipment developed in the United States, the Soviet Union, Germany and other countries. China conducted trials in 1958 and drilled its first mine shaft in 1969, gradually achieving independent development and expanding its applications to national defense, high-rise buildings, sewage treatment and other fields.
This paper focuses on customized demands for overseas markets, introducing four core products: TBM Cutters, Raise Boring Machine (RBM) Roller Cutters, Reverse Circulation Drilling (RCD) Roller Cutters, and Wear & Heat-Resistant Materials. It briefly describes their specifications, advantages, application scenarios and quality standards. The products are compatible with mainstream overseas equipment models, covering various industries and geological conditions. Adopting advanced manufacturing processes, all products are certified under ISO9001 and can be supported with relevant international certifications.OEM/ODM customization is available. Supported by an annual production capacity of 30,000 sets of cutters and over 10,000 tons of wear & heat-resistant materials, together with multilingual technical support and full-cycle after-sales service, the products fully meet the supporting requirements of complex overseas engineering projects.
With the steady advancement of global underground infrastructure construction, the wear-resistant material technology of shield tunneling machine tools is accelerating iteration and upgrading. Its performance level directly determines the operational efficiency of shield equipment and the control effect of the whole life cycle cost of projects. Currently, the innovation of wear-resistant materials for shield tunneling machine tools presents three core development directions: composite diversification, intelligent technology integration, and green remanufacturing, which will continue to promote the upgrading and improvement of tool products towards high performance and low carbonization.
