Opencast procedure

I have no experience in mining. I would gather a set of participants with knowledge about what happens and with sticky notes I would ask them to describe the main activities of the opencast process.

Then, for each main activity I would ask them to describe what is done, by whom, with what equipment, under which rules, using which records. Please check in the following free webinar on demand the use of the turtle diagram to collect information about a process - The Process Approach - What it is, why it is important, and how to do it - https://advisera.com/9001academy/webinar/iso-9001-process-approach-free-webinar-on-demand/
