矿山钻机常见故障排查与应急处置方案

发布时间:2026-06-19 00:09人气:
矿钻机械长期在粉尘大、湿度高、工况复杂的矿山环境作业,易出现卡钻、动力不足、渗漏、钻孔偏斜等各类故障,若处置不及时,不仅影响施工进度,还可能引发设备损坏、安全事故。掌握常见故障的排查方法与应急处置方案,是现场作业人员的必备技能。
卡钻是最常见的故障,多由岩层破碎、岩屑堆积、钻孔偏斜导致。轻微卡钻可通过正反旋转钻杆、低速退钻清理岩屑解决;严重卡钻需立即停机,严禁强行拉扯钻杆,通过高压风、水冲洗孔内岩渣,松动钻杆后缓慢退出,必要时拆解设备辅助脱困。动力不足故障,气动钻机多为气路压力不足、滤芯堵塞导致,需检查空压机压力、清理滤芯、检修气路密封;液压钻机多为液压油不足、管路渗漏、油泵故障,需补加液压油、修复渗漏点位、检修液压泵。
钻孔偏斜故障主要源于机身固定不牢、钻头磨损不均、岩层软硬不均,排查时需重新校准机身水平度、更换全新钻头,针对复杂岩层降低钻进速度。设备渗漏故障集中在管路接头、密封件位置,需及时更换老化密封垫、紧固接头螺栓。作业中突发异常震动、异响、压力骤变时,需立即停机断电断气,排查故障隐患,故障未彻底排除严禁复工,同时做好故障记录,便于后续预防性维护。
