斯维尔得洛夫无烟煤生产联合公司的多尔然斯卡亚大井第一期工程能够及时投产,在多方面取决于主井筒中和井塔上建筑安装工程的完工。这些工程包括井筒装备,井架的安装,沿井筒敷设8根动力电缆和2根信号电缆至610米水平,向Ⅰ号提煤设备的多绳提升机上悬挂头绳和尾绳及提升容器。 电缆的敷设拟定在井筒和井架装备工程结束后进行。按现行定额完成井筒的电缆安装需要30天。 井筒电缆安装的实施方案由建井工艺设计托拉斯伏罗希洛夫格勒综合设计处完成。 给设计人员提出的任务要求是:拟定能够在最短期间内完成井筒中敷设动力及信号电缆的工程施工工艺。 在一根载货钢丝绳上、下放两根电缆(甚至是闭合的非旋转结构)是非常困难的,因
The first phase of the Dorganskaya Dajing joint project at Sverdlov’s anthracite production unit can be put into operation on time, depending in many ways on the completion of the main shaft and tower construction and installation works. These projects include the installation of wellbore equipment and derrick, the laying of 8 power cables and 2 signal cables along the wellbore to the level of 610 meters, and the hoisting ropes and tail ropes and hoisting containers on the multi-hoist of No.1 coal handling equipment. The laying of cables is planned after the wellbore and derrick equipment project is completed. It takes 30 days to complete the wellbore cable installation at the current quota. The implementation of the wellbore cable installation was completed by the Torres Voroshilovgrad Integrated Design Office for Well Construction Process Design. The task requirements for designers are to: Formulate the engineering process that will enable the wellbore to lay power and signal cables in the shortest possible time. It is very difficult to drop two cables (even a closed, non-rotating structure) on a freight wire rope because
