由江西有色冶金研究所、南昌有色冶金设计院、重庆矿山机器厂试验安装,全国第一台PG—1型爬罐设备,于1983年11月进行首次急倾斜天井掘进取得成功。试验工作在大吉山矿467中段13~＃西巷道进行。天井泵高度为54米,长宽规格2.6×2.4米,天井质量完全符合设计要求,自始自终沿脉掘进,实现了天井掘进不丢脉,显示了在脉状矿床采用爬罐掘进天井的优越性,
It was successfully installed by the Jiangxi Non-ferrous Metallurgy Research Institute, Nanchang Non-ferrous Metallurgy Design Institute and Chongqing Mining Machinery Factory. The first PG-1 type climbing equipment in China was successfully carried out for the first time in the steeply pitching tunnel in November 1983. Experimental work is carried out in the middle of 467 Dajiashan Mine, No. 13 ~ West Lane. Patio pump height of 54 meters, length and width of 2.6 × 2.4 meters, the quality of the patio in full compliance with design requirements, starting from the end along the pulse of the tunnel, the realization of the tunnel excavation does not throw pulse, showing the use of canyon vein climbing tank tunneling Superiority,
