I. Customer Background
In a mining area in Chifeng City, Inner Mongolia, Mr. Liu, a mining area manager with over 30 years of experience, is leading his team in a "black-to-green" transformation. As the largest iron ore mining area in the region, this mining area has been exploited for half a century. While making contributions to the national economic construction, it has also left behind an ecological "scar" covering an area of 12.6 square kilometers - open-pit mines, waste rock dumps, tailings ponds and other mining sites are scattered across the mountains.
In 2023, with the full implementation of the Implementation Plan for Mine Environmental Governance in Inner Mongolia Autonomous Region, Mr. Liu voluntarily took on the ecological restoration task of the mining area. This abandoned mining area, covering an area of 85 hectares, has a fragmented terrain, exposed slopes and a vegetation coverage rate of less than 15%, making it a tough nut to crack in local ecological governance. Facing this arduous task, Liu Zhiqiang's team introduced two Komatsu PC210-11M0 excavators as the main construction equipment, embarking on a new journey of mining area ecological restoration.
II. Project Challenges
Complex Terrain + Environmental Protection + Diverse Construction Requirements
Key Words: Complex Terrain, Extreme Working Conditions
Complex terrain conditions: The mining area has multiple open-pit mines over 50 meters deep and steep slopes over 30 meters high. The terrain has significant height differences and steep slopes, limiting the operating space for machinery and posing high safety risks. Additionally, the loose waste rock piles are unstable and prone to landslides and collapses.
Stringent environmental protection requirements: As a national-level demonstration project for green mine construction, the project must adhere to the strictest environmental protection standards during the construction process. The high noise and emissions of traditional mining equipment are in stark contrast to the concept of ecological restoration. How to ensure construction efficiency while achieving green operations is a key challenge.
Diverse construction requirements: The restoration project involves multiple steps such as slope reduction and load reduction, site leveling, topsoil coverage, and vegetation restoration, each with different performance requirements for equipment. Particularly in slope treatment, it is necessary to ensure operational safety while achieving precise terrain shaping, which poses extremely high demands on equipment maneuverability.
Extreme operating conditions test: The geological conditions in the mining area are complex. The working surface often encounters hard rock mixed with loose waste rock piles. The equipment not only has to withstand the impact of hard rock conditions but also needs to prevent the sinking risk when operating on the loose materials. This poses a severe challenge to the adaptability and reliability of the equipment.
III. Equipment Application and Performance
Power and Stability: Equipped with a 123.2kW high-power engine that meets the national IV emission standards, the PC210-11M0 maintains strong power output even at an altitude of over 1,500 meters in the mining area. Its optimized hydraulic system and enhanced chassis design ensure the stability and safety of the equipment when operating on a 30-degree slope, perfectly adapting to the complex terrain of the mining area.
Precision Operating Capability: The intelligent hydraulic system equipped on the equipment enables precise flow control, allowing for centimeter-level accuracy during slope trimming. The unique "one-click force increase" function enables the equipment to maintain optimal working efficiency when dealing with different hardness materials, from loose waste rock to hard mineral rocks, and can handle them all with ease.
Environmental Performance: Compared to traditional mining equipment, the noise of the PC210-11M0 has been reduced by 15%, emissions have been decreased by 30%, fully meeting the environmental requirements of green mining. Its advanced fuel system reduces fuel consumption by 7% compared to the previous model, significantly reducing operating costs and carbon emissions during long-term operations.
Multifunctional Application: By quickly replacing different attachments, the PC210-11M0 can handle the entire process of crushing, loading, and fine leveling. It demonstrates strong excavation power during slope reduction and removal stages, achieves precise spreading during the topsoil coverage process, and completes detailed terrain shaping in vegetation restoration work, truly achieving multi-purpose operation with one machine.
IV. User Experience
Operational Comfort: The fully sealed and pressurized cab effectively blocks dust and noise from the mining area, and the ergonomically designed suspended seat and multi-directional adjustable control lever significantly reduce the fatigue of the operator. Even after 8 consecutive hours of slope work, the operator can still maintain a good working condition.
Reliability and Durability: The reinforced structural components and wear-resistant design specifically for mining conditions enable the equipment to perform well in harsh mining environments. The self-cleaning air filter system and dust-proof sealing design effectively extend the service life of key components, maintaining a 98% availability rate during a three-month high-intensity construction period.
Intelligent Management: Through the Komatsu Kanchis system, managers can monitor the equipment's location, working status, and health condition in real time, achieving scientific construction scheduling and preventive maintenance. The intelligent diagnostic system can alert potential faults in advance, minimizing downtime to the greatest extent.
Economic Benefits: The improvement in fuel economy enables each unit of equipment to save over 5,000 yuan in fuel costs per month, and the overall operating costs are reduced by 12% compared to expectations.
V. Customer Reviews
Master Wang, who has over 15 years of experience in operating mining equipment, said: "Working on slopes with temperatures of over 30 degrees always made me nervous, but the stability of the Komatsu excavator gave me full confidence. Its control response is extremely precise, enabling it to easily complete precise slope restoration operations."
