Industry Expertise

Servicing the Mining and Construction Industries

VDC offers innovative programs that help customers improve performance and outsource the burden of drilling and blasting.


Coal Surface Mine Production

VDC takes every step necessary to ensure your coal surface mine production project is completed on time and on budget.

Coal Surface Mine Production

Preventative maintenance

  • VDC’s 24/7 on-site maintenance program reduces drilling equipment failure and downtime and increases the life expectancy of equipment.
  • Technicians routinely sample and inspect equipment components to identify problems before they affect production.
  • Only factory-trained personnel service VDC equipment, enabling our suppliers to offer longer warranty periods that translate into lower operating costs.

Working efficiently

  • VDC stocks an inventory of commonly used drilling items on site (e.g. drilling bits, drill steel).
  • VDC tracks bit life and penetration rates to adjust drilling performance and reduce overall operating costs.

Maximizing resources

  • Our drilling crews are in constant communication with our blasting crews, sharing information that enables maximum rock breakage at minimal cost.
  • Blasting crews use an electronic explosive inventory tracking system that allows staff to focus on production at the job site.

Construction Site Preparation

VDC construction teams and surface mine production crews maximize efficiency by sharing all available resources.

Construction Site Preparation

Improving productivity

  • Construction clients are working under tight deadlines, so we implement steps to reduce downtime and increase production.
  • VDC measures bit life and penetration rates to calculate which bit-steel-drill combination will work best for the material we are removing.

Leveraging technology

  • Advanced computer simulations adjust burden and spacing requirements, enabling VDC to use fewer explosives and drill fewer holes.
  • VDC blasting crews use an advanced explosive tracking system.
  • VDC maintains an electronic inventory of commonly used drill parts at the job site.
