Looking at the future trend of underground mining from two kinds of equipment in sandvik

What is the future trend of underground mining?

With the continuous mining of the mine, the roadway will be deeper, narrower and the underground temperature will be more extreme, which will make the mining more challenging.

Mining companies will pay more and more attention to mining safety and environmental safety of employees, and it is bound to achieve zero harm, reduce emissions and save energy, and improve the working environment of operators to make them more comfortable and assured.

Faced with such challenges, what should sandvik do?

Find more economical drilling and drilling solutions to reduce the waste of overbreak cost in loading and transportation, anchoring and other aspects;

Improve the safety performance of equipment and let customers achieve zero accidents;

Develop the latest diesel engine to reduce carbon emissions and protect the environment;

Better ergonomic design makes operators more comfortable to work;

The equipment automation system helps operators to drill more easily and work more easily;

Remote control drilling solution brings more cost savings, higher productivity and improved safety.

The first battery-driven rock drill rig for walking.

In 2016, sandvik introduced the DD422iE automatic rock drill rig, which is the first rock drill rig driven by battery in mining industry, and integrates the freedom of operation of traditional diesel engine equipment and the main environmental, health and safety (EHS) advantages of electric equipment. It doesn't need a diesel engine, and the walking is powered by a battery. During the drilling process, the battery actively compensates the power supply of the power grid, so that the walking between tunnels can be completed.

This trolley used for underground drilling and roadway excavation relies on the mine power grid for drilling operation. In the process of rock drilling, the trolley will automatically charge the battery, so there is no need to charge it specially. In addition, walking downhill not only does not consume electricity, but also charges the battery of DD422iE in sandvik. The transmission system of this trolley can convert the kinetic energy of wheels into electric energy and store it in the battery. Compared with the traditional transmission system, another benefit is that it can reduce heat generation.

In addition to the new battery power system, the innovations of sandvik DD422iE include optional 3D scanning navigation function and improved new working arm. Navigation function can shorten the setting time at the beginning of each drilling cycle, automatically scan over-excavation and under-excavation, and provide valuable information to optimize drilling operation.

Intelligent working arm positioning and drilling control system can improve accuracy, shorten cycle time and reduce drilling cost. Optional 3D navigation function is compatible with iSURE drilling design and data software. The direct benefit of all these functions is to improve the efficiency of mine excavation, which is reflected in the increase of excavation meters per month.
