I was predicting a rise in RSA gold production. It was not much, but it was UP !! South African mines produced 395.2 tonnes of gold in 2002, a 0.4 percent rise on 2001 and the first increase in nine years due to higher metal prices and a weak rand, the Chamber of Mines said on Thursday FULL: biz.yahoo.com

In Manitoba, mining engineers noticed that falls of rock occurred at times when humidity was highest. Air from the surface carries water and it is changed several times a day. The water interacts with the slip planes of support rock and mobilizes them. The "seismic events" they talk about that killed the miners at the Wits, are called by miners "bumps", or rockbursts. They generally are heralded, as earthquake geologists know, by patterns of microseisms of an escalating nature over time. Most mines of a deep and extensive nature practice what is called rock mechanics and relief tunnel engineering to a degree, but at best they do only a cursory study of it. They do not indulge in it as a predictive science, that perhaps a Fourier could have developed, to prevent accident. No mine has a "thou shalt not mine at condition X days." They try to make the ground stable by various means but cannot tell you when the ground will give way. Inco tried to allow for what was called controlled degradation of pillars by sizing the pillars to a certain dimenions in the cut. This worked to a degree, but they left many dangerouys situations and the carnage of miners in the 70's from Sudbury was steady. This has abated because of lessened mining. Mines today also are also demanded a better safety record. At Inco some studies have suggested freezing fill and rock in order to stabilize the ground. This would negate the lubricative effects of humidity as well. Unfortunately only the placer miners have taken this technique to heart.

I really don't enjoy news of miners'(or anyone else's)death, just if production is impacted, we need to make note. On, somewhat, the other side of the same coin, thought someone other than myself would try to bring forward lines of positive & negative (demand & production) impact from the AIDs vaccine which seems to offer some level of protection to black & Asain populations. "This press release contains "forward-looking statements" within the meaning of the federal securities laws. These forward-looking statements include without limitation, statements regarding the outcome of any further analysis of the clinical data from this AIDSVAX trial, the timing and progress of completion of development efforts for AIDSVAX, the need for additional clinical trials to support licensure of AIDSVAX and the timing or ultimate outcome of FDA approval of AIDSVAX for use by individuals in racial subgroups or more broadly"... biz.yahoo.com
