1. On-site performance
What problems will the mining area see?
- The unit only has a problem with a filter element, belt, sensor or small electrical part, but it has to be shut down on site to wait for people, parts, and judgment.
- Maintenance time is delayed again and again until high temperature, low oil pressure, starting failure or abnormal alarms appear in a concentrated manner.
- After the maintenance personnel arrived at the scene, they found that tools, spare parts, and historical records were missing, so they could only temporarily disassemble and inspect the equipment and then reorder.
- Production, drainage or camp power supply all rely on the same set of units. As soon as the minor fault is stopped, the site immediately enters coordination and waiting.
2. Risk causes
The reasons behind the power layout
Many mining areas focus on whether the unit can be purchased and started, but do not consider common spare parts, maintenance intervals and on-site maintenance support as part of the power supply plan.
Downtime in remote mining areas is often not caused by the repair itself, but by the time extended by fault confirmation, spare parts search, procurement, transportation and personnel arrival. If a small item breaks, if the site is not prepared, it will turn into a wait of several days.
Without a maintenance plan, filters, belts, oil, cooling systems, batteries, sensors and control electrical components will be left unused, and small problems will accumulate and eventually turn into major shutdowns.
3. Scope of influence
Production suspension, fuel consumption, maintenance, safety and environmental protection will all be magnified
- The production line stops, drainage, communications, lighting or camp electricity may also be forced to downgrade, and on-site management pressure rises rapidly.
- Temporary procurement of spare parts and external maintenance costs more, transportation is slow, and quality and adaptation may not be confirmed immediately.
- Delayed maintenance will accelerate the wear and tear of the unit, and the number of fuel consumption, alarms and subsequent failures will increase.
- Faults that could have been handled in a few hours turned into days of downtime and production loss due to gaps in spare parts and maintenance plans.
4. How to avoid before construction
What do mine owners need to confirm in advance?
- Before putting into production, prepare common spare parts according to the unit model and operating hours. Do not wait until the first shutdown to start looking for filter elements, belts, sensors and electrical parts.
- Write the maintenance cycle into the on-site operation plan, and make it clear who records, who inspects, who replaces, and who is responsible for spare parts inventory.
- Prepare basic maintenance tools, common consumables, key electrical components and supply response methods for key units, especially in remote mining areas, leaving a margin in advance.
- Put the maintenance plan and the production plan together to avoid postponing maintenance in order to meet the production volume and eventually being forced to stop due to failure.
5. On-site confirmation information
The closer the information is to the scene, the faster the plan will be implemented
- Existing or planned unit model, serial number, operating hours, daily operating hours and load conditions.
- A spare parts list is currently available, including filters, belts, oil, sensors, controllers, AVRs, pumps and electrical components.
- Past fault type, downtime, waiting time, maintenance personnel arrival time and maintenance records.
- The distance from the mining area to the service point or spare parts warehouse, road conditions, the impact of rainy season and on-site staffing.
