在三山岛金矿新立辅助斜坡道高效施工过程中,设备的良好性能和较低的设备故障率是2项重要因素。为了提高铲运机的工作效率,采用在铲运机轮胎上安装防护链的方式来降低铲运机的维修停机时间,提高其设备完好率。经过近半年的实际应用,效果比较理想,取得了良好的综合效益。1 新立辅助斜坡道概况新立辅助斜坡道从新立矿区-176m水平与三山岛矿区-150m中段连通,通过三山岛矿区斜坡道出入地表,辅助斜坡道净断面(三心拱)为4.3m×3.4 m,斜坡道坡度为15%,岩石性质属花岗岩,硬度f=8～12,作业面岩石节理发育不完全。基建期掘进到-400
In the Sanshandao Gold Mine new auxiliary ramp efficient construction process, the equipment’s good performance and low equipment failure rate are two important factors. In order to improve the working efficiency of the scraper, the scraper is equipped with a protection chain on the scraper to reduce maintenance and downtime of the scraper and improve the equipment intact rate. After nearly six months of practical application, the effect is quite satisfactory and good comprehensive benefits have been achieved. 1 Xinli Auxiliary Ramp Overview The Xinli Auxiliary Ramp is connected to the mid-150m section of Sanshandao Mining Area through the slope of Sanshandao Mining Area at a level of -176m from Xinli Mines, with a net section (three-hearted arch) of auxiliary ramps of 4.3m × 3.4 m, slope gradient of 15%, the nature of rock is granite, hardness f = 8 ~ 12, the working face rock joints development is not complete.
