I have PM you
This is a working record, kept probably to reconcile royalty payments due to the mineral owners (this is in the days before state ownership of common minerals such as coal, iron or fireclay) by the Garside's.
When the York Road Coal & Iron Co. abandoned Killingbeck Colliery in 1885 they had a statutory obligation to submit abandonment plans for each seam worked at the colliery detailing the extent of the workings. These were submitted to the Home Office and formed an archive of abandonment plans, aimed at avoiding unnecessary risk of collieries encountering flooding workings (this followed a series of flooding incidents known as inrushes resulting in disastrous loss of lives). Over the years these abandonment plans became more and more detailed, as a consequence of the lessons learnt from one mining disaster after another. Of relevance locally was the catostrophic inrush incident at Lofthouse Colliery when a face encountered flooded old workings and the subsequent inrush resulted in the loss of seven lives. This incident resulted in an exhaustive trawl of all known sources of records by the NCB to ensure that all possible records were researched and used minimise the risk to colliers. These records are now held by the Coal Authority and are all in the public domain (sadly for a fee).
Unfortunately as good as these records are, the sacrifice made by the four colliers killed at the Gleision Colliery in South Wales on 15th September 2011 demonstrated the scale of risk that remains for all working below ground from flooded old workings!
The plans may be dirty but it never went below ground!
Colliery surveyors always completed their surveys using notebooks to record their surveys using mining dials (a simple robust theodolite to set-out angles and to record the angle of workings from a known point), surveyors levels to measure difference in height and precisely measured chains to measure distance. All this information was transcribed and calculated to add details to record plans.
The grime on the plan is the impact of years of the dust in the surveyors office, grime worn in by many surveyors elbows and general wear and tear!
