Method of mechanising the backfilling work in roadway support operations by using the same building material for sealing and cavity filling using pumping and by means of controlling the setting behaviour |
| 摘要 |
<p>For the backfilling of roadway support structures in a pumping process with hydraulically setting building materials a formulation is proposed which uses alpha hemihydrate and allows the backfilling cavity to be sealed with the same building material with adapted control of the setting behaviour.</p> |
