Abstract

The article presents brief description and results of laboratory and in-situ tests of frame support with backfilling of behind-anchoring space with grout. Characteristics of mining and geological conditions on the site of inclined conveyor shaft of Sychevskiy-I mine-section, A.D. Ruban Mine (JSC SUEK-Kuzbass) has been given. Grouting quality has been tested according to described technology, strength characteristics of cement and degree of grout mix influence on the surrounding rock mass has been determined. It is figured out that reinforced canvas use as a between-frame overlap increases cement strength. Some recommendations regarding the use of reinforced canvas as a grouting material have been formulated.
