described mine filling system, described tailings storehouse connects ore dressing plant by the mine tailing waste pipe, on described mine tailing waste pipe, oil isolation pump is installed, and described mine tailing waste pipe is also installed cyclone between oil isolation pump and ore dressing plant.
described mine filling system, described agitator connects content gauge, and described content gauge connects described central control system.
described mine filling system, described tailings storehouse, fine coal ash silo, sandstone storehouse are connected level-sensing device with cement bin, and described level-sensing device connects described central control system.
described mine filling system, described pipeline adopts wear-resistant steel pipe.
a kind of placement method of mine filling system, at first prepare filling slurry at bottom surface filling preparation station, then be transported to dead zone to be filled by pipeline, carry out filling, the continuous data of each measuring equipment in stowing operation, be aggregated into central control system, and, with reference to the designing requirement index, carry out the automatic control of each ingredient to guarantee the stable operation of filling manufacturing process.
the placement method of described mine filling system, the continuous data of described each measuring equipment is to measure by level-sensing device the storage capacity that level-sensing device that tailings storehouse, fine coal ash silo, sandstone storehouse and cement bin install records, and is transferred to central control system; Described flow meter is measured the flow of filling slurry in agitator, and described densimeter is measured the concentration of filling slurry, and in described content gauge mensuration agitator, the liquid level level is to prevent empty bucket or to overflow.
beneficial effect:
1. the transportation concentration of classified tailings filling process of the present invention is 65%～70%, classified tailings utilize be generally+37 μ m of particle diameter, utilization rate is generally 50%.The level-sensing device that whole filling system utilization is arranged on each feed bin records terminal data, transfers to after central control system and carries out and set numeric ratio, makes stowing operation more accurate, laborsaving.
2. in cement bin of the present invention, the mining with filling material of splendid attire forms cemented fill with mortar parcel piece stone, have for single block of stone of mortar parcel, form firm cemented fill, and piece stone is positioned at stope central authorities and surrounding is wrapped up by mortar, form these two benefits of the cementing integral body with integrated support ability and self-reliance of a kind of " outwardly strong but inwardly weak ".And piece stone particle diameter is generally less than 300mm.Mortar is generally fine sand slurry or last mortar.Because the part mortar in obturation is substituted by piece stone, not only improved the bulk strength of obturation, and can significantly reduce filling cost.This technique is carried respectively down-hole by piece stone and mortar, transfers to stope and is mixed to form adhesive bond (therefore generally being applicable to large stope filling).If mine has the barren rock of peeling off of excavating plant can be for utilizing, benefit more is worth significantly.
