Electric Autonomous Haul Trucks Prove Their Worth After 3 Years – How Automation Is Reshaping Mine-to-Crusher Economics

Why a three-year record of zero accidents, zero emissions, and 1.04x human efficiency is changing how quarry and mine operators think about equipment investment

In November 2022, a fleet of 14 pure-electric autonomous haul trucks began full operation at the TCC Jurong limestone mine in Jiangsu Province. Three years later, that decision has proven to be one of the most consequential in the mine's history. The fleet has operated safely for three consecutive years with zero accidents, zero emissions, and zero drivers on board. The autonomous trucks have achieved an efficiency rate of 1.04 times that of manual operations, while generating cumulative savings of tens of millions of yuan. With 7×16 hours of continuous daily operation, the project has become the longest-running pure-electric, fully autonomous mining truck operation in the world. For quarry operators, aggregate producers, and mining companies facing rising labour costs, tightening safety regulations, and increasing pressure to reduce carbon emissions, this milestone offers a compelling real-world case study. At OCP Mechanical Company, with over 40 years of manufacturing experience, we supply a comprehensive range of crushing and screening equipment – including PE Series jaw crushers, HST Series cone crushers, and mobile crushing plants – designed to integrate seamlessly with modern, automated mining operations, all at factory-direct prices.

The driver shortage problem – why automation is no longer optional

The challenges facing the mining and quarrying industry are not just about equipment performance – they are increasingly about people. At the TCC Jurong mine, the shift to autonomous haulage was driven by a pressing reality: an aging workforce of truck drivers, combined with difficulty in recruiting younger talent. At the same time, tightening safety regulations following major industrial incidents created additional pressure to find safer operating methods. The traditional model of manual haulage had reached its limits in both safety and efficiency. Autonomous driving in closed industrial environments emerged as the solution. For quarry operators facing similar labour challenges, the Jurong project demonstrates that automation is not just a technological upgrade – it is a strategic response to a fundamental workforce shortage. The ability to operate 16 hours a day, seven days a week, without reliance on human drivers, transforms the economics of a quarry operation. At OCP Mechanical, we understand that the shift toward automation requires equipment that can keep pace. Our crushing and screening solutions are designed for high availability and consistent performance, complementing automated haulage systems to create a fully integrated, efficient operation.

Zero accidents, zero emissions, zero drivers – the three pillars of success

The Jurong project has achieved what many in the industry considered impossible: three years of continuous operation with zero accidents, zero emissions, and zero drivers. The safety record alone – over one million kilometres of zero-accident operation – is a powerful testament to the reliability of autonomous technology in demanding mining environments. The trucks navigate dusty conditions, variable weather, and complex interactions with other equipment while maintaining stable performance. The zero-emissions achievement reflects the environmental benefits of electric powertrains, which eliminate diesel exhaust and reduce the carbon footprint of haulage operations. The project has also cut annual diesel use by 800 metric tons and carbon emissions by over 1,800 metric tons, saving RMB 6.12 million yearly. The zero-driver model addresses the persistent challenge of finding and retaining qualified operators, enabling the mine to operate 16 hours per day without relying on shift workers. For quarry operators evaluating automation, these three pillars provide a clear framework for assessing the potential benefits. OCP Mechanical's equipment is engineered to support safe, efficient, and sustainable operations, with robust designs and energy-efficient drive systems that align with the goals of modern, automated mines.

1.04x human efficiency – the productivity case for automation

One of the most compelling findings from the Jurong project is that autonomous haulage has achieved efficiency 1.04 times that of human drivers. This productivity gain, certified by China's National Institute of Metrology, demonstrates that automation is not a compromise on performance – it is an improvement. The trucks operate 16 hours per day, seven days per week, without breaks, shift changes, or the variability inherent in manual operation. They maintain consistent speed and routing, reducing fuel consumption and tire wear. For quarry operators, this productivity gain translates directly into lower cost per tonne – a critical metric in competitive aggregates markets. The ability to achieve human-equivalent or better efficiency while eliminating labour costs and reducing downtime creates a compelling financial case for automation. At OCP Mechanical, we help operators maximise the productivity of their entire processing chain. Our PE Series jaw crushers, HST Series cone crushers, and VSI 6X sand making machines are engineered for high throughput and consistent product quality, ensuring that the material delivered by autonomous trucks is processed efficiently and cost-effectively.

From pilot project to industry standard – the path to wider adoption

What began as a pioneering collaboration between TCC Jurong and CiDi has now become a blueprint for the wider industry. The success at Jurong has led to repeated orders from TCC, with the technology now deployed across multiple sites. The CiDi autonomous mining solution has been adopted at more than 20 mines across China, covering coal, metal, and aggregate operations. This expansion demonstrates that autonomous haulage is not a one-off experiment – it is a proven technology that is being adopted across the industry. For quarry operators considering automation, the Jurong project provides a clear reference case. The technology works, the productivity is proven, and the safety and environmental benefits are substantial. The challenge now is integrating autonomous haulage with the rest of the processing chain – from primary crushing to final product screening. OCP Mechanical's comprehensive range of crushing and screening equipment is designed to work seamlessly with automated material handling systems, enabling operators to build a fully integrated, efficient processing line. Our factory-direct model ensures that you get the equipment you need at competitive prices, backed by responsive after-sales support.
