Great information, many thanks. I just started a first borehole in Uganda with a borehole machine. How do I stop borehole cave in? After drilling the length of the extension drill pipe, the next pipe only goes in about half way thru. We then have to screw it in manually before starting the machine again. We are using Polymer when drilling but it does not have much effect on keeping the borehole walls from caving in. Thanks a bunch, your advise is well appreciated
