LAUNCH: COAL MINING ROCK ENGINEERING BOOK
The publication 'Rock Engineering for Underground Coal Mining' (ISBN 1-919 783-34-2) was launched at a cocktail party held in Witbank on 25 April 2002.
The launch was attended by the Deputy Chief Inspector of the DME, Piet Botha, the SAIMM
President, Alistair Douglas, mining officials, SAIMM members, SACMA office bearers, Wits Technikon students, and SIMRAC members and researchers.
In his welcoming address, Duncan Adams of SIMRAC Project Support Services told delegates that the need for the book was identified in 1993 and listed as SIMRAC project COL 001 by the SIMCOL Advisory Group. In 1999 project COL 606 was finally contracted to CSIR Mining Technology.
The book was co-authored by Nielen van der Merwe and Bernard Madden and published and printed by the South African Institute for Mining and Metallurgy (SAIMM).
The book is available from the SAIMM. Contact Karen du Toit at phone number 27 834 1273 to order a copy.

Training symposium held on improved x-ray reading for mining medical officers
About 30 mine medical officials attended the training symposium held on Saturday 16 February 2002 in Johannesburg as part of project HEALTH 803, 'Radiological occupational lung disease surveillance' (ROLDS), in an endeavour to improve x-ray reading skills for medical personnel in the mining industry. The programme is focused on developing distance-based training materials and the evaluation of skills. For more information, please contact Professor Neil White at the University of Cape Town Lung Institute, telephone number 021 406 6850 or 021 404 4360.

SIMRAC Research Programme for 2002 - 2003
The SIMRAC research programme for 2002 was approved on 27 February 2002 at a total cost of R39, 327 million.
Note: New projects are now listed according to thrust areas, unlike the earlier numbering system using an alphanumerical order based on commodities. The new numbering system of 6 digits, for example 02 01 01 refers to the specific year of the project, i.e. 2002, the first thrust area 01, i.e. Behavioural safety, and the number of the project in that thrust, namely 01.

Doctoral study on ionising radiation co-funded by SIMRAC
The Cape Technikon conferred its first doctoral degree on Kathy Meehan for her dissertation on the effects of exposure to continuous low doses of ionising radiation on bats.
SIMRAC partly sponsored the work.
In her study Dr. Meehan studied the effects of radiation emanating from disused Monazite mines near Steenkampskraal in the Northern Cape on the endangered Cape bat, Rhinolophus capensis. (See photo below).
In a comparative study using unexposed bats, Dr. Meehan was able to determine that exposed bats show signs of dose dependent DNA damage, evidence of abnormal bone structure and a marked decrease in osteoid mineralisation which is an indicator of myelodysplastic syndrome, a progenitor to haematopoietic cancers.
