Description
Technical field
The invention belongs to coal mine filling production technique fields, and it is cementing closely knit to be particularly suitable for a kind of underworkings gangue
The method of filling.
Background technique
China is in coal industry great development period, and coal mine filling production technique makes rapid progress, according to filling material used
Material is different with mode of movement, and the filling process of China's application mainly has dry stowing, slush, consolidated fill, filling-up pneumatically
Deng especially consolidated fill is widely applied in underground mine, nonferrous metal mine.
The filling method is to mix cementitious material with solid materials such as gangue, flyash, improves consolidating for obturation
Change intensity, when filling, rushes object gravity flow filling process using water and mixture slurry is flow to goaf, the glue in controllable time
Knot, cohesion, reach filling design strength, to realize bashing deformation controlling for rock surrounding gateways, avoid surface subsidence.Because filling is starched
Body rushes the gravity flow of object fluid by water and is fills up to the realization sold stowing of excavating lane lower part, but goaf upper space exists
Gap and uncompacted problem especially cannot achieve sold stowing in the upper Delta Region in nearly horizontal filling face, cause to fill
Triangle cannot sufficiently connect top and the low problem of pack effectiveness on lane.
Summary of the invention
In order to solve the problems, such as goaf upper space, there are gaps and uncompacted, especially solve in nearly horizontal filling
The upper Delta Region in face cannot achieve sold stowing, cause triangle on filling lane that cannot sufficiently connect top and the low difficulty of pack effectiveness
Topic, the present invention provide the method that a kind of pair of underworkings carries out sold stowing.
In order to adapt to the above method, present invention simultaneously provides a set of filling systems.
