老庙矿在1960年参照华銅銅矿小型架綫式电机車的結构,自己設計、制造了銅庙—15型电机車,应用在井下支巷及地表短程运輸中,效果很好。在此以前,老庙矿的井下支巷及地表短程运輸,全部是人力推車。由于矿車損坏情况严重,同时又采用自制的滾柱軸承,人力推車十分吃力;而线路坡度达8‰的地表短程运輸,放重車下坡速度很高,經常掉道,还有撞人的危险,推空上坡非常費力,当时运輸工效仅2.4(吨·公里/工班)。当使用銅庙—15型电机車之后,运輸的落后面貌大大改观,到1963年底,已經有占总运輸量70％的人
In 1960, Laomiao Mine designed and manufactured Tongmiao -15 electric locomotive in light of the structure of Huacai copper mine small wire electric locomotive, which has good effect in downhole branches and surface short-range transportation. Prior to this, the old mine tunnel mine underground surface and short-range transport, all human cart. As the car damage is serious, but also with self-made roller bearings, human cart is very difficult; and the line slope up to 8 ‰ surface short-range transport, heavy truck downhill speed is high, often off the road, and It was very labor-intensive to push people uphill, at a time when the transport efficiency was only 2.4 (t · km / work). After using the Temple -15 electric locomotive, the backwardness of transport has been greatly improved. By the end of 1963, 70% of the total transport volume had already been obtained
