在北哈萨克斯坦,露天矿开采工艺的特点是,广泛使用СВШ-250МН型牙轮钻机,穿孔效果和生产能力取决于这种钻机的可靠性。СВШ-250МН型钻机很适应索科洛夫-萨尔拜和杰蒂加林采选公司的各种生产条件。这两个采选公司露天矿所钻岩石的坚固性变化范围很大,而且气候恶劣,根据生产条件,对钻机的可靠性(即钻机的可靠性特征、故障特征及原因)进行研究是一项紧迫的课
In northern Kazakhstan, the open-pit mining process is characterized by the extensive use of the СВШ-250МН-type roller-driller, the perforation effect and productivity depending on the rig’s reliability. The СВШ-250МН rig is well adapted to the production conditions of the Sokolov-Saalbeh and Jidigalin mining companies. The ruggedness of rock drilled in the open pit mines of these two mining companies varies widely and their weather is poor. Based on the conditions of production, the reliability of the drilling rig (ie, the reliability characteristics, failure characteristics and causes of the rig) is studied Urgent class
