Requirements for mining locomotive batteries

There are several important features for underground mining locomotive batteries which are dictated by the working environment. The problem areas for the mining locomotive batteries and the solutions offered by Microtex in the mining locomotive battery range are listed below:

  • Reliability – there must be an absolute guarantee that the battery provides the rated performance from day one of installation. Mining companies cannot afford a single incident of not meeting a working day’s production or take a chance with any aspect of safety. For this, quality control at each stage of mining locomotive battery manufacture and final safety checks are essential. Microtex takes this responsibility very seriously and under their ISO 9000 accreditation, have ensured that every manufacturing stage and every component is checked for electrical, chemical and physical properties. The final product mining locomotive battery is 100% tested for both performance and safety.
  • Ease of installation – when fitting a traction battery underground, often with limited space, there should be minimal skill and effort required. For this reason, Microtex supply the traction battery pre-assembled with charging plugs, fully tested and at top of charge ready to make a complete operational shift. The lifting eyes of the container are positioned to provide maximum stability when hoisted into and out of the loco battery compartment.
  • Operation – the mining locomotive batteries should have enough capacity over their lifetime to deal with the operational requirements and maintenance should be minimal. In addition, the traction batteries must not overheat. Overheating leads to greater water loss, shorter working life from grid corrosion and greater gas evolution on charge. To ensure good operational characteristics, Microtex use traction batteries whose plates have a tubular construction. This is an important design principle as amongst other advantages, it provides the highest energy density of all lead-acid battery constructions.

Safety concerns in mining locomotive battery

Safety – fire and explosions are the two main worries attached to battery powered underground mining equipment. Regarding explosions, the most common cause attributable to batteries is that of internal arcing when the mining locomotive battery has completed or is near the end of its charging cycle. Arcing can occur inside a mining locomotive battery if there are weak or inadequate joints between lead alloy components, often between the internal bus bar and the plates. 

A spark generated here due to switching current on or off, or even a jolting movement of the loco, in association with a high hydrogen concentration from charging, will result in an explosion. This is why the welding processes in the Microtex mining locomotive battery assembly procedures are monitored and the bus bar and plate weld for every cell are inspected before passing to the next stage. There is also a random destructive test carried out each shift to test the integrity of these critical welds.

Sizing a mining locomotive battery

Battery sizing options – an important aspect of ensuring a long and trouble-free service life is to install a correctly sized mining locomotive battery. Matching the capacity to the operating cycle is key in obtaining the best value for money and the lowest TCO. The standard mining locomotive battery sizes offered by Microtex are comprehensive. There is also flexibility for capacity and cost options within the standard batteries due to the variety of sizes within the tubular traction 2v battery range. The 2v cells are offered in DIN and BS dimensions with a high capacity rating.

How much does a locomotive battery cost?

Locomotive battery cost is related to the voltage and Ah of the battery requirement. Please contact our sales team who will answer your queries promptly. Get in touch with the Microtex Sales team.
