Not even close. At -1020 m (Bob Gulden's figure of record,
<http://www.caverbob.com/wdeep.htm>) (-1026 m in Sun report), Qikeng Dong is
83rd deepest in the world. Deepest is Krubera /Voronja at -2191 m, more than
_twice_ as deep! Qikeng Dong is the first 1000-m deep cave in China, however.
>Miao Keng (known as China's big shaft) is a 506 metre deep shaft
According to Gulden's list <http://www.caverbob.com/pit.htm> it is a
491-m shaft, which is the figure Erin Lynch gives. She keeps the database of
the Tianxing caves. It is number 7 in Gulden's list. There is even another
one in China that is deeper. Deepest is Vrtoglavica in Slovenia at 603 m. I
know that some of the deeper shafts are open to the surface, although Bob does
not note that in his list. It is possible this is the deepest in-cave shaft.
