Gangue Grouting Filling - China

price: contact company for price

Process introduction

Gangue grouting filling process generally refers to that the

mixed cementing material slurry is conveyed to the worked-

out section after filling the worked-out section with

gangue, to make the material slurry gradually penetrate the

whole coal gangue filling body by using its good fluidity,

thereby forming good cementing strength.

Our company designed and constructed the filling system for

Shandong Xinwen Mining Group Zhaizhen Coal Mine, which aims

to effectively control surface subsidence and liberate the

unexploited coal resources under industrial plaza.

Meanwhile, it can solve the safety, environment, land use

and other problems of gangue hill.

This technology has won national scientific and

technological progress second award and provincial

departmental scientific and technological progress first

award.

Technical innovation:

Gangue grouting filling technology can achieve that the

gangue or waste rock is not risen out of the mineshaft by

carrying out underground filling. Besides, it is designed

and equipped with filling tamping hydraulic support.

Adopting the new alkali-activated material can effectively

improve the fluidity and stability of material slurry.

Reasonable slurrying process can effectively enhance the

permeability of material slurry.

Adopting the new-type precipitator underground can

effectively reduce the amount of dust underground and

improve the mineshaft environment.
