The Vehicle in the picture is one of our pure electric driverless Vehicles.，No.6051……”The field equipment engineers were excited to introduce.。“At present, this pure electric driverless mine car has been running 1100 kilometers in Zijinshan Gold and Copper Mine.，It is providing samples for the construction of smart mines.。”

Meet the challenge / Challenges

Facing the increasingly serious transportation safety challenges and the shortage of human resources in the global mining industry.，The company actively responds to the needs of industry change.，But how to make this large Vehicle achieve precise control is a technical difficulty in the field of automatic driving.。

Technical test / technical testing

The company took the lead in loading in Jinzhong open-pit mining project in Inner Mongolia.、Drive、Obstacle bypass、Unloading and other aspects of testing and simulation of production work.，The applicability of the unmanned driving system in metal mines was successfully verified.。

In May this year，The company has further strengthened cooperation with Zijinshan Gold and Copper Mine and other units.，The unmanned transportation project was officially launched in the open-pit mining project.。Carefully prepared and rigorously tested，The project was formally put into trial production on May 18.，Up to now, it has accumulated more than 1100 kilometers of safe operation.，Demonstrated good technical strength and stability。

Technical optimization / technical optimization

In operation practice，In view of the special climatic conditions of rainy and foggy Zijin Mountain,，The project team strengthened the mine car's ability to perceive rain and fog.，With an advanced positioning system、Perception system and precise control system，The stability control and passing ability of mine cars on wet and slippery roads and waterlogged roads have been significantly improved.。

At the same time，Facing the complex working environment such as narrow space，The mine car can flow smoothly、Precise、Smooth completion of backing into position、Turn around and change direction、Precise docking、Automatic dump、Trajectory run、A series of highly difficult actions such as autonomous obstacle avoidance and multi-vehicle dynamic interaction.。Pecially in the ore pass process.，The mine car has achieved centimeter-level precise parking.，The safety and efficiency of the unloading process are greatly improved.。

With a number of pure electric driverless mine cars officially stationed in Zijinshan open-pit mining area.，These mine cars will be further marshalled on the basis of the previous test cars.，To verify its safe and efficient performance in the complex operating environment of the mining area.。

Future，The company will continue to intensify technological innovation and intelligent upgrading.，Timely promotion of wide application of unmanned driving technology in mine operation，Comprehensively improve the automation and intelligence level of mine operation。
