Case Study 1: USA Mining Exploration Company Increased Drilling Efficiency with Advanced Core Rig
Customer Background: A Professional Mining Service Provider in the American Market
A mining exploration company from the United States contacted YG because they needed more efficient drilling equipment for their expanding exploration projects. The company has been operating in the North American mining and geological investigation market for more than 15 years. The customer’s company scale includes around 70 employees, 5 professional geological exploration teams, experienced drilling engineers, and project managers, etc. The company mainly serves mining enterprises, construction contractors, and geological consulting companies in the United States. After comparing several suppliers and communicating with different core drilling rig manufacturers, the customer finally chose YG’s vertical shaft drilling solution.
Customer Challenges: Old Equipment Could Not Meet Modern Exploration Requirements
Before purchasing the new equipment, the customer faced several problems that affected project efficiency.
1. Low Drilling Efficiency in Hard Rock Areas
Most of the customer’s projects were located in mining regions with complicated geological conditions.
The main problems included:
- Slow drilling speed
- Frequent equipment adjustment
- Low daily drilling depth
- Long project completion periods
In some projects, the old machines could only drill around 30-35 meters per day. This limited the company’s ability to accept more exploration contracts.
2. Poor Core Sample Quality Affected Geological Analysis
For mining exploration, core samples are extremely important.
However, the customer found that their old equipment sometimes produced:
- Broken rock samples
- Incomplete cores
- Low recovery rates
Because of this, engineers needed additional time for investigation, which increased project costs. The customer needed core drilling equipment that could provide stable drilling and high-quality samples.
3. High Maintenance Costs and Long Downtime
The old equipment required frequent repairs.
Common issues included:
- Mechanical component wear
- Drill rod damage
- Unexpected machine shutdowns
- High spare parts costs
Every equipment failure delayed project schedules and increased labor expenses.
