我矿夏桥三号井(付井)提升采用2BM3000/1520型卷扬机,该卷扬机是建井期间使用的临时设备,在安装期间井筒提升中线与滚筒中线偏差200毫米,投产时又作为正式提升卷扬机移交生产。 付井原设计使用单层双车罐笼,钢绳直径31毫米,当时余绳460毫米,使用部份净宽度为1040毫米,因此当时外偏角为1°15′,未发生越槽现象。(见图一)
The No. 3 mine in Xiaqiao (pay well) was upgraded with the 2BM3000 / 1520 hoist, a temporary equipment used during the well construction period. During the installation, the wellbore centerline and the drum centerline deviation was increased by 200 mm. During the operation, it was also hoisted as an official hoist Hand over production. In the original design of the well, a single-layer double-car cage was used. The diameter of the steel rope was 31 mm. At that time, the remaining rope was 460 mm wide and the net width of the part used was 1040 mm. Therefore, the out-going angle was 1 ° 15 ’at that time. (See figure I)
