The use of slurry density, torque and speed can be useful in detecting clogging. Abstract ''Clogging'' is a common issue encountered during tunnelling in clayey soils which can impede tunnel excavation, cause unplanned downtimes and lead to significant additional project costs.

What is a Mineral Deposit by Definition

 · Mineral Deposits The valuable minerals sought by the prospector are probably always present in all rocks, but are generally so scattered and diffused as to be useless. Even in sea-water, gold can always be detected, and appreciable quantities have been found in granite, syenite, basalt, diabase, marble, and mud, quite apart from any workable ore deposits.
