I have been underground in cut-down Landcruisers in chromite mines in South Africa. Not the very deep gold mines, where ventilation certainly is a problem. These are drift mines, where you can just drive in. Because the chromite seams are rather thin (in some of the mines just 1.6 to 1.8 metres) they cut off all the superstructure so that the highest point on the vehicle is the top of the steering wheel - and the driver's helmet ! Passengers crouch in the seats or lie in the back. Ventilation in these mines is quite good, as they have enough entrances to get good air movement. I didn't notice any particular problem with exhaust fumes. Diesel vehicles are quite commonly used in underground mines that have good ventilation and no fire hazard (i.e. not coal mines!). In the UK they are used for example at Winsford salt mine, and many years ago in my student days (1960s) I drove an ordinary petrol mini-van underground in the gypsum mine at East Leake, where the archival drill-core store was in a disused area of the mine. - Steve Henley ------------------------------------------------------- Dr Stephen Henley Resources Computing International Ltd Matlock, Derbyshire, UK http://www.SiliconDale.com ------------------------------------------------------- ----- Original Message ----- From: "Keith Ramsey" <[log in to unmask]> To: <[log in to unmask]> Sent: Tuesday, March 11, 2003 3:29 AM Subject: Toyota Landcruisers > Today's issue of "The Guardian" has a roadtest of the Toyota Landcruiser in > which it is claimed that some models have been used underground in mines in > South Africa, presumably for haulage.
