Holmebank Chert Mine

Holmebank Chert Mine
Fan Entrance lock installation 9th January 2018

Today I was up at Holmebank Chert Mine near Bakewell on behalf of the Derbyshire Caving Association and the Peak Instructed Caving Affiliation. One of the access points to the mine required a new locking mechanism which allowed explorers to access the locking bolt from inside and out.

Using some high strength steel components bought by the DCA, I fabricated up a simple rotating hatch, allowing a person to reach through and access the sliding bolt on the inside of the gate. The hatch is locked with a combination padlock and cavers can obtain the code from the usual source. Currently it is set to the same combination as the other lock on the top entrance.

Many thanks to Ewan Cameron from Evolution Outdoors for the company and assistance installing the hatch today and of course to Joe at the architects firm for his continued support of access to the mine for outdoor centres and instructor training.
