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 *0%**8%, 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 *0% 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, ***1.

Technical innovation:

 u  It is the first domestic company who puts forward “slurry-like-paste” gravity-flowed filling technology.

{ u  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.

{ u  High degree of automation; central control system can carry out remote commissioning and system maintenance through network; full unattended;

{ uIt adopts the new-type cementing filling material with self-developed and independent intellectual property.

{ u  Simple and reasonable process; advanced system; small investment of energy infrastructure; low integrated operation cost.
