Abstract：The second and third phase of the Hongqinghe coal mine are mainly coal roadway.It is intended to be built by the central No.2 manhole.In order to realize the safe and efficient construction of the project,the coal flow system design program was selected combining with construction experience,which determined to use mixed transformation program and sinking coal bunker structure,and the construction scheme of parallel operation in the coal bunker system.Finally,the parallel operation of the coal bunker system was realized,reducing the duration of the project and the amount of engineering to ensure the upgrading capacity.The technology has been successfully applied in the construction of Hongqinghe Coal Mine and other coal mines,which can provide references for similar engineering practice.
