In the coal mining operations in Inner Mongolia, a coal mine faces extremely challenging mining conditions. The white sandstone encountered in its coal mining face has a hardness grade of F12-13, and the high-strength rock characteristics impose stringent requirements on the performance of the cutting picks. Although the Shanghai Tiandi shearer used by the coal mine operates continuously, the issue of cutting pick wear severely restricts production efficiency and economic benefits.

For a long time, the coal mine has made numerous attempts in the selection of cutting picks. However, constrained by the high strength and high wear resistance of white sandstone, traditional cutting picks frequently experience issues such as excessive wear and structural fractures during actual mining operations. The high frequency of cutting pick replacement not only significantly increases production costs but also leads to extended unnecessary downtime of mining equipment, significantly impacting overall coal mining progress and creating a major bottleneck in improving production efficiency.

Faced with this dilemma, the Du'erbote U170 cutting pick became the key to the coal mine's breakthrough. Du'erbote Company attached great importance to this cooperation project, fully considering the project's timeliness requirements, and decisively adopted air freight to ensure the U170 cutting picks were delivered to the coal mine site as quickly as possible.

After the U170 cutting picks were installed on the Shanghai Tiandi shearer, they were immediately put into high-intensity coal mining operations. Leveraging mature design concepts and high-quality material craftsmanship, they demonstrated outstanding performance during continuous cutting and impact processes with high-hardness white sandstone. Based on actual production data monitoring and statistical analysis, compared to previously used cutting pick products, the consumption of U170 cutting picks was reduced by 20%. This achievement not only effectively reduced cutting pick procurement costs but also significantly shortened equipment downtime caused by cutting pick replacement, greatly improving coal mining operation efficiency.

The relevant person in charge of the coal mine highly praised the Du'erbote U170 cutting picks: "Under the complex conditions of high-hardness white sandstone, the Du'erbote U170 cutting picks demonstrated excellent adaptability and reliability. Their significant results in reducing consumption and increasing efficiency have created tangible economic benefits for the enterprise. In future cutting pick procurement, we will prioritize Du'erbote products."

The successful application of Du'erbote U170 cutting picks in this Inner Mongolia coal mine fully validates their technical advantages and product strength in dealing with complex high-hardness rock formations. In the future, Du'erbote Company will continue to increase R&D investment, deepen its expertise in cutting pick technology, and strive to provide the coal mining industry with more high-performance, high-quality cutting pick products, further promoting the industry's production efficiency and technological level.
