Time:2025-12-26From:sinorock View:

Sinorock provided innovative self-drilling anchor bolt pipe roof support technology and a comprehensive technical solution to a gold mine in Xinjiang, China, successfully overcoming extreme geological challenges and ensuring underground safety throughout the project.

Challenge: Complex and Extreme Geological Conditions

Complex and Extreme Geological Conditions

The Xinjiang gold mine faced severe geological challenges, including highly weathered, intensely altered, and extremely fractured rock formations. The area was characterized by uncertain extension lengths and highly unpredictable locations due to these geological issues. Throughout the project, the mine encountered numerous hazards, including rock falls, roof collapses, and mud inflows, resulting in more than 50 incidents in total. These problems severely impacted the construction schedule, causing the project construction to be affected for more than 500 days, and the utilization rate of the steel arch frames in the roadways reached as high as 43.9%. Every inch of excavation presented enormous challenges.

Sinorock’s Full-Spectrum Solution

In response to these difficulties, Sinorock provided a comprehensive solution, adopting self-drilling anchor bolts for pipe roof support technology. We continually optimized existing support techniques and tailored our solution to the mine's specific geological conditions. Our solution also included full-section rigid support technology to enhance safety and stability during the excavation process.

This innovative technology effectively ensured the safety and efficiency of the excavation operations, overcoming challenges posed by highly fractured and mud-filled soft rock formations.

Results: Significant Advancement in Excavation Progress

Significant Advancement in Excavation Progress

Sinorock’s advanced support technology played a crucial role in dramatically improving excavation progress at the mine. The excavation speed reached new heights, with monthly excavation rates surpassing 700 meters and the total excavation distance for the year hitting 6.000 meters. This success not only ensured the completion of the project on schedule but also demonstrated the effectiveness of our tailored solutions in high-risk environments.

With Sinorock’s robust technical support and innovative solutions, the gold mine was able to tackle numerous construction challenges, securing the safety and smooth operation of underground mining activities.

Application Advantages

Adaptability to Complex Geological Conditions

Self-drilling anchor bolt pipe roof support technology effectively addresses common complex geological conditions in mines, such as highly weathered, intensely altered, and severely fractured rock formations. Its unique integrated drilling and support system allows for rapid stabilization in soft rock or water-bearing strata, avoiding safety risks associated with traditional support methods.

Shortened Construction Time and Increased Efficiency

Compared to traditional support techniques, self-drilling anchor bolt pipe roof support technology offers significant improvements in construction efficiency. By reducing the time required for drilling and installing supports, construction cycles are greatly shortened. This technology is especially advantageous in high-risk environments, where it accelerates progress and increases monthly excavation rates, ensuring timely project completion.

Shortened Construction Time and Increased Efficiency

Enhanced Safety and Stability

The combination of self-drilling anchor bolts and pipe roof support provides comprehensive rigid support, significantly enhancing the overall stability of mine tunnels. This technology is particularly effective in high-stress areas and unstable rock formations, preventing safety accidents such as rock falls and tunnel collapses, ensuring the safety of construction workers.

Cost Control and Economic Benefits

Self-drilling anchor bolt pipe roof support technology reduces material consumption and optimizes the construction process, resulting in lower overall construction costs. By minimizing labor, material waste, and equipment usage, the technology enhances the economic efficiency of the entire project, offering a high cost-performance ratio.

Long-Term Reliability

By tightly integrating the support system with the rock mass, this technology provides stronger and more durable support. Through long-term practical application, self-drilling anchor bolt pipe roof support systems have been proven to maintain stable performance over extended periods, extending the service life of tunnels and providing a solid foundation for long-term mine operations.

Long-Term Reliability

Environmental Friendliness and Sustainability

Compared to traditional support methods, self-drilling anchor bolt pipe roof support technology uses more environmentally friendly materials and construction techniques, reducing its impact on the environment. Additionally, the shortened construction cycle leads to lower energy consumption, contributing to the sustainable development of mining projects.

Conclusion

The successful application of Sinorock's self-drilling anchor bolt pipe roof support technology in the Xinjiang gold mine project demonstrates its strong adaptability and efficiency in complex and extreme geological conditions. Through innovative technical solutions, Sinorock effectively addressed safety risks such as fractured rock layers and roof collapses, while significantly improving excavation progress and ensuring the project was completed on schedule. The technology not only shortened construction cycles and reduced costs but also enhanced the long-term stability and safety of the mining operation. Sinorock's technological advantages provide reliable support solutions for the mining industry and offer valuable practical experience for construction in high-risk environments, further promoting the sustainable development of the industry.
