Abstract:Aimed at the problems existing in dealing with mine drainage emergency in our country, the disadvantage of the relayed drainage system composed by original entirely tubular axial-flow submerged pump and large-scale mine submerged pump is analyzed. A new relayed drainage system made up by oil-filled mixed-flow submerge pump and large-scale mine submerged pump is put forward. The merits of this system is thec haracteristics ofs trongd raina bility,r eliableo perationt hrought rial-productiona nds pot-operation,i t can solve the problems of deep and big runoff drainage, availability and security for the resuming exploitation of the submerged underground coal nine, iron ore, etc
