义煤公司常村煤矿二水平行人副斜井是连接一水平和二水平的主要巷道之一。巷道为半圆拱断面,锚喷支护,净宽4 200 mm,净高3 500 mm,斜长750 m,倾角为18°,上下平台各30 m。斜井原用于罐车提升运输人员,绞车型号为2JK-2/20,电动机为JR系列,电压为380 V,属高耗能电动机,且无“MA”标志。另外,斜井还存在绞车超期服役、滚筒齿轮间隙大、传动不平稳、减速机渗油严重、维修量大等问题。为此,煤矿对斜井人员运输设备进行改造,以架空乘人装置替代斜井罐车运送人员。
Yichang Coal Company Changcun Coal Mine two horizontal pedestrian inclined shaft is connected to one level and two levels of one of the main roadway. The roadway is semicircular arch with anchor and shotcrete support. The net width is 4 200 mm, the height is 3 500 mm, the inclined length is 750 m, the inclination is 18 °, and the upper and lower platforms are each 30 m. Inclined shaft was originally used for tanker lift transporter, winch model 2JK-2/20, the motor is JR series, the voltage is 380 V, is a high energy-consuming motor, and no “MA ” logo. In addition, there are inclined shaft service overtime winch, drum gear gap, transmission is not smooth, heavy gear oil leakage, maintenance and other issues. To this end, coal mines on the shaft personnel transport equipment to transform the overhead crew to replace inclined shaft tanker transporting personnel.
