In 1953 Southern Rhodesia's (Zimbabwe's) only coal mine, Wankie Collie
ry, was taken over by the Anglo American Corporation of South Africa.
The colliery's new owners soon discovered that the elimination of ''ha
nd lashing'' (shovelling of coal) was the key to better productivity a
nd expanded output. Coal cutting machinery was installed wherever poss
ible, but in the colliery's two oldest shafts existing mining methods
were too deeply entrenched and consequently too expensive simply to be
swept away. Instead Anglo American attempted to reinforce colonial pr
oduction relations. Supervision underground was tightened up, and the
degree of ''self-regulation'' enjoyed by lashers in determining the am
ount of work they did was limited. The introduction of a new mine tub
designed to increase productivity precipitated strike action in Februa
ry 1954 by the colliery's entire black labour force.
