Abandoned mine workings manual (RP940)

In 1984 CIRIA published SP32 Construction over abandoned mine workings. It was a seminal publication which is still widely used by industry some 30 years after it was published. A project to update the guide has been underway for several years. The new manual (C758) is considerably more than an update of SP32 as it has been expanded, both in scope and content and significantly rewritten. The revised manual also addresses many new areas where practices and principles are emergent and have required considerable discussion amongst the Project Steering Group. 

We will announce the launch of this revised publication (C758) in 2019 - please check the CIRIA website for updates.

Project status

Given the wealth of information contained in the new manual, as principal funders of the work, The Coal Authority have agreed with CIRIA that the chapter drafts are made available to the community prior to finalisation. The draft guides can be found here.
