Abstract: According to the present serious stuation of the cal poduction igher than the demands in order to realize a low cost.low energy consumption.good safety and high etficient production.based on the conventional mine producion mode and the Bulianta Mine as a case the paper introduced the practical appication plan ofPSl techmnology in he mine podution A secondar develogment was conducted on the PSl system.The quick startup of the belt conveyor interace and " one-touch reset and oter function of the integrated interace for the muiti belt conveyors and major water drainage punmp were expanded.The practical appication resuls of the PStechnoicgy inBuliand Mine showed tht the PSl technology combined with the mine production and management could realize the mining excavation,machinery;rans:oration and veitlation and other each producton link to be integrated to a platform. which could fmely handle each problem ocured in the poducion pocess coud mprove the operation efic ency and relia ility of the system.could reducethe idle running time of the equipment and couid maximell reduce the enegy consumption.7depend on the intelligent technology and information system,the personel activtites and distrbuton contion aswell as th equioment operation con.tions n the underground mine could be timely montored and the safety of the personnel operation and the equipment operation could be improved.
