Analysing the Hazards

摘要

The short answer to the above question is: 'Well, that depends on what materials you are quarrying and how steep your excavations and tips are'. Under the current Quarry Regulations 1999 geotechnical assessments of excavations and tips are required if any excavations or tips are classified as constituting a 'significant hazard'. Regulation 33 of the Regulations defines hazards as significant if such a failure would directly or indirectly be:rn1. liable to endanger premises, roadways or other places where people are likely to be found off site; orrn2. likely to kilt or seriously injure anyone.
