1. Improve Work Efficiency
   - Mechanized operation: The hole filling machine adopts a mechanized operation method, replacing traditional manual filling and significantly improving the speed and efficiency of hole filling. This is particularly important in scenarios such as large open-pit mines that require a large number of holes to be filled, as it can greatly reduce the preparation time for blasting operations.
   - Quick filling: Under normal circumstances, one working cycle of the hole filling machine can fill a blast hole. If a single cycle does not fill the hole, a second cycle can be performed until the desired result is achieved. This efficient filling capability helps to accelerate the entire blasting process.
2. Enhance Filling Quality
   - Accurate filling: The hole filling machine ensures that blast holes are filled evenly and densely through precise mechanical operation, thereby improving blasting effectiveness. In contrast, manual filling often results in uneven and poorly compacted fills, affecting blasting quality.
   - Reduce errors: Mechanized operation reduces errors caused by human factors, making hole filling more precise and reliable.
3. Reduce Labor Intensity and Costs
   - Decrease labor requirements: The hole filling machine replaces a significant amount of manual labor, allowing mining companies to reduce the number of personnel required for hole filling operations and thereby lower labor costs.
   - Improve working environment: Mechanized operation keeps workers away from dusty and harsh environments, protecting their health. It also reduces the risk of occupational diseases caused by long-term heavy physical labor.
4. Improve Safety
   - Reduce safety hazards: The hole filling machine reduces safety risks associated with manual operations, such as falls and collisions. Additionally, mechanized operation can reduce the risk of blasting accidents caused by human negligence.
   - Ensure personnel safety: Hole filling is one of the key steps in blasting operations. Using a hole filling machine can minimize the number of staff in the blasting area, thus reducing the risk of personnel injury.
5. Flexibility and Adaptability
   - Easy modification: The hole filling machine is typically modified from existing mechanical vehicles (such as loaders), with a relatively simple and low-cost modification process. This allows mining companies to select the appropriate vehicle for modification based on their specific needs.
   - Suitable for various scenarios: The hole filling machine is applicable to various blasting operation scenarios in open-pit mines, whether in large or small mines, and can leverage its efficient and precise filling capabilities.
