我矿从一九五六年建矿以来,直到一九六八年,出窿矿石进入选厂矿仓,全是手工倒矿。每当两个主平窿同时出矿,仅倒矿一个工班就需劳力十人。不仅劳动强度大,工效低(一个班最多倒矿400车),而且很不安全,曾多次发生车、人掉入矿仓的事故。 为了改变这种落后且不安全的状况,我矿于一九六九年元旦,试制成功一种简易可行的倒矿机械——侧轨式自动倒矿机。当即交付生产使用,并在使用中不断加以改善。十多年来的使用实践证明,该机较其它已定型的倒矿机械,更适合我矿生产的实际,效果比较显著。
Since my mine was built in 1956, mine has gone out into ore mills for ore processing factories until 1968, all by hand. Whenever two main holes at the same time out of ore, only a working class overturning required labor ten people. Not only labor-intensive, low efficiency (down to a class of up to 400 cars), but also very unsafe, has repeatedly occurred cars, people fall into the mine accident. In order to change this backward and insecure situation, I successfully trial-produced a simple and feasible down-pusher machine, the side-track automatic ore-handling machine, on New Year’s Day in 1969. Immediate delivery of production and use, and continue to be improved. More than 10 years of use proved that the machine is more than the other laid down mine machinery, mine more suitable for the actual production, the effect is more significant.
