1958年顿涅茨加里宁矿井建成了苏联第一个多绳提升装置的塔式井架。目前已投产和正在施工的塔式井架大约增加到30个,还有更多的塔式井架正在设计。钢筋混凝土的和钢结构的塔式井架是一个庞大的结构物,塔身高60—100米,建筑容积15000—40000多米~3。井架承受很大的荷载作用,总共有数千顿。目前塔式井架的造价比普通地面单绳绞车井架的造价大9—11倍。因塔身大小以及基础的条件不同,所以造价在
In 1958 the Donets Kalinin mine was completed with the tower derrick of the first Soviet multi-rope lift. There are about 30 tower derricks currently in production and under construction, and more are being designed. The tower derrick of reinforced concrete and steel structure is a huge structure, the tower height of 60-100 meters, the building volume of 15000-40000 meters ~ 3. The derrick is under a heavy load, for a total of several thousand tons. At present, the cost of tower derrick is 9-11 times greater than the cost of common ground single rope winch derrick. Because of the size of the tower and the basic conditions, so the cost in
