Ongoing Projects

Location: Embilipitiya, Sri Lanka

Extent: The extent of the project area was 26 Hectares  

Physiography: High elevation and difficult terrain

Scope of Work:

1. Geological Exploration:

• Geological investigation to demarcate ore reserves of dolomite, calcite (Marble), and the waste rock material.
• Preparation of a geological map at a scale of 1: 5,000 in addition to the topographic map, in both electronic and paper.
• Chemical analysis of the raw material to identify quality, grade, and possible industrial applications.

2. Ore Reserve Estimation

• Carrying out a drone survey to develop a Digital Elevation Model (DEM) of the area
• Carrying out Total Station Survey to quantify caved/mined areas.
• Ore reserve estimation through the drone mapping, total station survey & photogrammetry software tools.

3. Mining site safety assessment and Safety plan
   • Identification of existing safety issues and plan for eliminating hazards due to irregular mining activities.
   • Existing safety issues–Geo-Hazards, Groundwater and Unsystematic excavations of underground galleries and chambers
   • Assessment of the conditions of host rock and the supportive system
   • Safety establishment for all operatives
   • Proposal for safety enhancement for the surrounding community

4. Mine development
   • Mine site preparation and infrastructure development plan
   • Drilling, charging, blasting, secondary disintegration, and mucking proposal.
   • Proposal for the usage of waste rock

5. Production and disintegration plan
   • Estimation of solid rock quantity required for blasting in mine development work
   • Setting the preparational stage for mining – Removal of Overlying Rock Span
   • Overburden / Waste rock removal in the mining process/stage
   • Development of operational time frames for drilling, blasting mucking, and product transportation activities.
   • Employment of product disintegration and processing activities.

6. Traffic Analysis
   • Designing the access roads into the mine and out from the mine site
   • Drawing up the anticipated road maintenance plan

7. Manpower employment proposal and utilization of machinery and equipment
   • Planning for Manpower engagement for mining operations
   • Reassessment of machinery and equipment requirements

8. Impact analysis and adoption of remedial measures
   • Preparation of tailings /mine waste disposal
   • Identification of anticipated sociological influence of proposed mining activities

9. Mine closure and mine site rehabilitation proposal

• Drawing up the mine closure and rehabilitation plan

10. Detailed Proposals for Corporate Social Responsibility (CSR)

• Drawing up recommendations for corporate social responsibility

Activities accomplished

• Geology of the ore deposit
• Ore reserve estimation
• Existing Mine Safety issues
• Mine development plan
