  • Slurry Like Paste Cementing Filling - China

    price: contact company for price

    Slurry-like-paste cementing filling

    Process introduction:

    Slurry-like-paste cementing filling process generally

    utilizes the strong absorption feature of fly ash or fine

    aggregate, increases the slurry volume concentration while

    keeping the quality concentration at 70%-78%, makes the

    filling slurry be complete suspension state in piping,

    thereby reducing the bleeding rate of stope filling body and

    improving the filling body strength.

    The filling system designed by our company for Shandong

    Energy Feicheng Mining Group CaoZhuang Coal Mine adopts the

    “slurry-like-paste” technology, which uses coal gangue,

    fly ash and solid plastic agent according to the ratio of

    3:3:1, to produce the “slurry like paste” filling material

    with 70% mass concentration.

    The filling material can flow naturally to stope through

    drilling and underground laying piping, the whole system

    from material adding, mixing, stirring and transportation

    applies automation and control and achieves that one roadway

    serves for an exploration area, which can reduce thousand

    tons of tunneling ratio and manpower. In a word, the system

    possesses the advantages of simple operation, high filling

    speed, reliable operation and good filling effect.

    This project is rated as the international leading level by

    Shandong Science and Technology Agency in December, 2011.

    Technical innovation:

     It is the first domestic company who puts forward

    “slurry-like-paste” gravity-flowed filling technology.

     The “slurry-like-paste” process can achieve

    gravity-flowed conveying technology of that piping is not

    blocked under high concentration critical flow resistance

    and not segregated under low concentration.

     High degree of automation; central control system

    can carry out remote commissioning and system maintenance

    through network; full unattended;

     It adopts the new-type cementing filling material

    with self-developed and independent intellectual property.

     Simple and reasonable process; advanced system;

    small investment of energy infrastructure; low integrated

    operation cost.
