Hoang Quoc Bao
Field analyst
Bao spends most weeks on benches and in site offices, copying shift sheets and walking haul roads before any chart is drawn.
The office behind the site visits
Panel Birchhub Company Limited is the registered business name. The firm was established in 2014 in Ho Chi Minh City to sit with quarry and pit crews and turn shift records into charts the operations meeting can use.
A short history
In 2014 the founders were already walking limestone benches in the Mekong provinces, helping superintendents settle arguments between pit counts and the plant scale. Formal registration as Panel Birchhub Company Limited followed that same year, with rooms in Binh Chanh District so field notes could be turned into printed packs without living on a laptop in a pickup.
The work stayed close to mining output monitoring and equipment utilization analysis: watching loaders, haul trucks, and crushers, coding delays with the shift bosses, and returning with charts rather than a speech about method. By 2018 the monthly briefing had become a regular request from plants that already had a first study on the shelf. The office still keeps paper folders for each site, because a rainy Thursday in Binh Thuan is easier to discuss when the original sheet is in the room.
How we work
We introduce ourselves to the crew before we open a notebook. Delay codes are agreed in the language the radio already uses. Charts that would require inventing a travel time are left with a gap. Findings meetings happen at the site office when we can, and in Binh Chanh when the owner prefers the city.
People
Mai Thanh Ha
Mining engineer
Ha leads findings meetings, translating delay codes into language the superintendent and the owner can both use.
Dang Tuan Kiet
Charting lead
Kiet prepares the printed packs in Binh Chanh, checking pit counts against weighbridge tickets before a study leaves the office.
What we hold to
Safety holds after a blast stay in their own column. Incomplete sheets stay incomplete. The superintendent owns the introduction to the crew. Those habits are how mining output monitoring and equipment utilization analysis stays useful on a Vietnamese pit rather than becoming a tidy fiction.
