三山岛金矿的山特维克M1F型凿岩台车于1999年投入使用,经1万多h的使用,因设备老化,作业效率低下,故障率较高。由于井下作业环境潮湿,涌水量大,水分中氯离子含量超过海水,造成凿岩台车锈蚀严重,承重部位裂纹变形。因大部分备件厂家已不再生产,采购比较困难。为了提高作业效率,延长设备使用寿命,该矿对M1F型凿岩台车进行了技术改造。
Sanshandao Gold Sandvik M1F-type rock drill trolley put into use in 1999, after more than 10,000 h of use, due to aging equipment, operating efficiency is low, the failure rate is higher. As the downhole operating environment is humid, water inflow is large, the chloride ion content in the water exceeds that of the sea water, causing serious rusting of the rock drilling trolley and cracking of the load-bearing part. Because most of the spare parts manufacturers are no longer manufactured, procurement is more difficult. In order to improve work efficiency, extend equipment life, the mine on the M1F-type rock drilling rig technology transformation.
