Greetings:

I've been reading Mr. Hampton's posts for several days now.

I don't pretend to be a mining engineer, but I've been in and around enough mines over the past quarter century to know roughly what one looks like when I trip over it. :-)

For what it's worth...I concur with his musings, estimates, and reasoning in this and other posts. I've been using a minimum height of 3 metres for most of my calculations. Perhaps 3.5 is more realistic...perhaps not.

I'm sure a good mining engineer could and will concoct a design to minimize the mining height in most areas.

I am still thinking drift and fill, not having any great confidence in the strength of kimberlite. Time will tell on that score.

Regards,

WillP
