TECHNOLOGY OPTIMIZATION

AMNT has been undergoing various aspects of mining activities by applying bold thinking in action. Thereby this has resulted in a significant increase in productivity and operational efficiency. The company’s key to success in operational excellence is achieved through teamwork and its employees’ motivation to keep moving forward. Therefore, AMNT emphasizes its commitment to human resources and starts by providing various training and programs to create a healthy, balanced, and comfortable life dedicated to all employees. 

AMNT also optimizes technology to increase productivity and improve work safety. Several technologies that are being implemented include:

  • The application of cabin cameras in haul trucks to detect fatigue.
  • The use of speed cameras and optimization of jigsaw mining software to ensure compliance with speed limits.
  • Innovative badge technology with GPS, which has various safety and emergency features.

The adoption of this technology is accompanied by the provision of hard skills and soft skills for all employees.

PRODUCTIVITY ACHIEVEMENTS

One of AMMAN’s core values ​​is EXCELLENCE, where all employees will relentlessly pursue excellence and quality in everything they do.

MINING PROCESS

Mine Planning

Various mine plannings are set by the company, starting from production targets, are production scheduling, mine design that will determine pit boundaries, stockpiles and Waste Dump areas, as well as heavy machinery equipment to achieve the production targets.

Drilling and Blasting

After planning, the designated mine production area will be drilled and blasted, to obtain samples that meet the company’s production and commercial needs.

Material Sampling

The company’s laboratory will examine the sampling of rock drilling powder, which will be used as the basis for classifying economical materials (ore) or covering materials.

Loading

Mine products are loaded into haul trucks by loading machinery such as shovel.

Sorting

Fresh ore material with economic value is crushed in a crusher and sent to the processing plant via a conveyor belt to be processed into concentrate. Ore that cannot be processed due to limited processing capacity is sent to the stockpile area for further processing. Meanwhile, the overburden is sent to the waste dump area.
