Cement Quarries Drilling and Blasting

Course Code: CI 05

 Course Overview

This course has been developed to quarry operation.

Quarrying is the breaking of the rock in a safe and economic way and transporting the result to a plant for further reduction in size. This involves planning, purchasing of suitable equipment, drilling, blasting, loading and transport of rock in quantities sufficient to permit the continuous operation of the cement plant. All this must be accomplished as efficiently and safely as possible to maximize the return on investment. Finally environmental considerations must be remembered and careful control kept on noise and dust levels. Parts of the quarry that become worked out must be rehabilitated so that there are few scars on the landscape.

 

Course Objective

After completing this course participants will have:

  • The General basics of Geology (Elements, Minerals, types of rocks & Rocks for the cement industry).
  • The nature of cement raw material.
  • In-depth understanding of the.

- Drilling.

- Blasting.

- Types of Explosive.

- Explosive Initiation Systems.

- Environmental Effects of Blasting.

- Secondary Breaking.

  • Quarries machinery and Evaluation of quarry machinery.
  • The skills in daily quarry operation will be improved.
  • Familiarize the trainees with principals of crushing, the types of crushers and Crushing Operation.

 

Target Audience

  • This course will have a particular focus for people working in the Cement Quarries operation and process control Engineers, Quarries supervisors, Quarries technicians, Cement Quality control and laboratory engineers.
