我矿使用沈阳矿山机械厂制造的3.4×8米重型板式给矿机,将溜井的矿石传送到翻斗车里。自1969年投产以来轨板经常开焊,全新轨板一般不到二个月就又得更换一半(30块),而且工人劳动强度大,工作条件差。据统计,轨板开焊影响给矿机开动台时25%,占总维修时间的60%多,成为影响矿石输出的一大难关。工人两班倒维修不过来,还得经常连零点班,弄得精疲力尽,结果还是经常停产。
The mine used the 3.4 × 8-meter heavy-duty plate feeder from Shenyang Mining Machinery Factory to transfer the ore from the slipway to the dump truck. Since 1969 put into operation since the rail often open welding, the new rail generally less than two months to be replaced by half (30), and workers labor-intensive, poor working conditions. According to statistics, the influence of the welding of the rail slab on the operation of the mining machine is 25%, accounting for more than 60% of the total maintenance time, becoming a major obstacle affecting ore output. However, the workers failed to repair the two shifts. They often had to work at zero shifts and were exhausted. The result was often discontinued.
