(Teversal Colliery Closed After 111 Years - Continued)


Seams worked at Teversal were Top Hard around 5 feet to 5 feet 6 inches (1.5m to 1.68m) thick 1869-Apr 1948, seam exhausted, Dunsil varied between 2 feet (0.60 m) and 4 feet (1.22m) 1871-1873, 1918-1919, 1921-1922 proving, 1924 - June 28, 1935/36 - Aug 1968 a total of 37 panels, plus several exploratory heads, all handfilled, as the seam varied too much in thickness to be mechanised, the intergrown dirt at the base of the seam being variable thickness and of no commercial value and also in parts, top coal had to be left to form a good safe roof, due to potholes 2 or 3 yards (1.8 or 2.5m) that created treacherous roof conditions, the edges of which being called slickensides (a very shiny slippy surface with no adhesion power at all). As seen in the photo access to the face under the lip was extremely tight. Severe weighting was experienced when Dunsil faces were approaching Top Hard pillar edges 30 yards (27.5m) above and we used to notify the Manager and Undermanager in advance so that extra timber / supplies could be available. Similarly Waterloo workings under Dunsil pillar edges at 10 yards (9m) above and sometimes the Waterloo faces were affected by Top Hard workings 40 yards (37m) above. Reference is made later to water from Top Hard old workings.

Squaring the panel sometimes gave weighting and crashing and banging when the first weight break happened. Squaring is where the panel has advanced the same distance approximately as the length of the face. Of course there were others as the panels advanced and it certainly made you jump if you were nearby. I experienced a big one in the Dunsil seam but I cannot remember which face but it was either 50s or 60s. One minute you could see quite a way down the gobbing between the packs and next minute a frightening bang and shuddering and clouds of dust and the gobbing seemed to be filled with stone. All the colliers on the face were watching the props for any sign of movement and getting ready to run or crawl away smartish as it was possible that props could fly out with the extra weight being thrust onto the face line. With total caving on the modern machine faces it was probably worse.

Sometimes the potholes in the Dunsil seam roof above the coal although generally a couple of yards (2m) long some were up to 10 yards (9m) across or more and could extend over 3 stints. Washout conditions prevailed also in several areas. But of course successive managers were most reluctant to leave top coals up and every effort was made to take it down as soon as possible when conditions improved slightly as it meant extra tonnage. The last Dunsil face 150s with a face gradient of about 1in4 on the Brimington anticline finished on 27th August 1968. And the seam was abandoned in 1969 albeit that quite a few roadways were used as access to the 1st Waterloo seam workings. This was stated and accepted by the HMI providing no further Dunsil coal was extracted.

Some Top Hard Panel numbers: (refer to some others mentioned previously in 1916 and 1918). North Level (finished 1887) leading to Hardwick Dips (about 2 miles inbye)

North dips

South Level leading to the Far end, just over 2 miles inbye (to 1930) South Dips (2¼ miles in), Skegby Dips, leading to 123s, 5s (to 1932), 34s, 105s, 72s, 74s dip, 2s, 21s level, 53s off Skegby Dips (to 1936) 2¼ miles inbye (had a main and tail haulage system on 1in7 grade)
66s Jazz to right (to 1930), with Brimington anticline, leading to 68s (1930s), 79s (to 1933) 2½ miles inbye

40s Main Road to right (very steep at 1in4 to 1940) leading to 4s (finished 1942) about 2½ miles inbye
112s Main Road (1928 -1944) leading to 17s (finished 1940-41)
17s (finished 1943) about 3 miles inbye
70s (fininished 1946)

Last panel 114s to left at bottom end, just under 3 miles inbye from pit bottom (finished Apr 1948, abandonment of seam). A roadway was driven in Top Hard from Nov 1960 – July 1964 and a few tons were extracted whilst straightening out an old return roadway to prepare for a new pit bottom at No2 Shonkey shaft. An amendment on the Top Hard abandonment plan was made and duly signed by Bernard Bailey (2728), Surveyor and countersigned by the Manager George Noble (5852).

    new drifts at 1in6 and 1in3 were driven to access seam June 1941-Apr 1942, from the Top Hard South Level, however the coal was in a swilley and because the tubs would not run properly, roof ripping into rock was dropped into the floor to the extent of 15 feet (4.5m) to level the road out, some of the roof and sides being unsupported and opened
