Study of ventilation reversion of airflow in mining

The CFD modelling were validated by mining roadway measurements using anemometers, methanometers and oxymeters. It has been proved that the mining roadway or tunnel longitude reached by the reversion of airflow is reduced by installing an auxiliary forcing ventilation overlapped with the main ventilation. Additionally, it has been determined that

Glossary of Mining Terms Coal Education

A. Abutment In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.

Double Shield TBM Herrenknecht AG

The auxiliary thrust cylinders serve only to secure the position of the concrete segments placed. When the stroke is completed, the gripper shoes are loosened and the gripper shield is pushed behind the front shield using the auxiliary thrust cylinders. Regripping lasts only a few minutes, which means that tunnelling is almost continuous.
