Slurry Like Paste Cementing Filling - Chinaprice: contact company for price
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.
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
