Mtundu wa nyali yachitetezo cha migodi ndi mtundu watsopano wa nyali wokonda zachilengedwe, womwe umatengera 1w LED yapamwamba kwambiri yopangidwa ndi Lumileds Lighting Company ndi mabatire a nickel hydrogen.Nyali yamtundu wotereyi ingagwiritsidwe ntchito pamalo oyaka komanso ophulika monga migodi ya malasha, makampani opanga mankhwala, mafuta ndi mayendedwe apamsewu, itha kugwiritsidwanso ntchito m'malo ena owunikira mafoni.Nyali yamtundu wa mgodiyo ili ndi satifiketi yosayaka moto yovomerezedwa ndi National Coal Mining Machinery Quality Supervision and Testing Center.

Pogwiritsa ntchito LED monga gwero lalikulu la kuwala, nyaliyo sifunikira kusintha gwero la kuwala panthawi ya moyo wa nyali ya mgodi.Pakalipano, chifukwa cha kutentha kwabwino kwa kapu yachitsulo yachitsulo, kutentha kwa gwero la ntchito kumakhala kochepa, moyo wautali, wotetezeka komanso wodalirika.

Mtundu watsopano wa zolipiritsa ndi kutulutsa zoteteza zitha kugwiritsidwa ntchito kuteteza kuchulukitsitsa ndi kutulutsa mopitilira muyeso ndikuwongolera moyo wa batri.Pakadutsa nthawi yayifupi, magetsi amatha kudulidwa mwachangu, ndipo ntchitoyo imatha kuyambiranso pambuyo pothetsa mavuto kuti atsimikizire kugwiritsidwa ntchito motetezeka.
