Design of Mining and Production Plan for Calcite-Dolomite (Marble) Quarry Complex, Embilipitiya, Sri Lanka.

LocationEmbilipitiya, 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.
  1. 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.
  1. 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
  1. Mine development
    • Mine site preparation and infrastructure development plan
    • Drilling, charging, blasting, secondary disintegration, and mucking proposal.
    • Proposal for the usage of waste rock
  1. 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.
  1. Traffic Analysis
    • Designing the access roads into the mine and out from the mine site
    • Drawing up the anticipated road maintenance plan
  1. Manpower employment proposal and utilization of machinery and equipment
    • Planning for Manpower engagement for mining operations
    • Reassessment of machinery and equipment requirements
  1. Impact analysis and adoption of remedial measures
    • Preparation of tailings /mine waste disposal
    • Identification of anticipated sociological influence of proposed mining activities
  1. Mine closure and mine site rehabilitation proposal
  • Drawing up the mine closure and rehabilitation plan
  1. Detailed Proposals for Corporate Social Responsibility (CSR)
  • Drawing up recommendations for corporate social responsibility
