Backfill drilling is a widely adopted high efficiency mining method in modern mine, borehole backfilling is the key in backfilling system. Beside the physical property of medium transported, the mechanical property of the system and the material property of pipeline, the construction quality such as borehole deviation and some others are the decisive factors to service life of the backfilling borehole. The filling times line is main basis for design of backfill drilling hole, the construction method and process quality control are the key to ensure the quality. Based on the analysis on the factors affected on service life of backfill drilling hole and the construction difficulties, the paper summed up and introduced the construction method of backfill drilling hole and the measures for quality control.
