How To Estimate RQD using Joint Count, Joint Spacing, and Joint Frequency | Problems and Solutions

During field surveys of rock slopes and walls, it is important to obtain the characteristics of rock joints because they affect the stability of rock mass. Rock joints are typically presented as sets of discontinuities (on average, three sets of discontinuities will be common in most rock walls). Watch this video that shows how to identify sets of discontinuities in the vertical rock wall in the field • Video . There are simple correlations that can be used to estimate RQD using the data on joint spacing and joint counts. This video gives three examples on how to do so.

So good, I would like to see the detail of outcrops that you explane too.

Hi sir i need joint number count formula in per meter cube for RQD calculations means you explained joint spacing formula but i need joint count number formula
Thank you

Sir! Your videos are very informative and we learn a-lot from them but your some videos are private so we can’t watch these videos please consider my request so that we can watch your private videos.
Thanks

Dear sir, i cant watch the video of how to identify sets of discontinuities in the vertical rock wall as it's set as a private video
