Our project consumed huge amount of work, research and dedication. Still, implementation would not have been possible if we did not have a support of many respected persons, who deserve our greatest gratitude. Therefore we would like to extend our sincere gratitude to all of them. We would like to show our gratitude Dr.Abdelaziem Abdelaal, Course Instructor, Head Of Mining Department for giving us a good guideline throughout numerous consultations. We would also like to expand our deepest gratitude to all those who have directly and indirectly guided us in writing this assignment. Many Thanks for all people, our collegues and team members itself, have made valuable comment suggestions on this proposal which gave us an inspiration to improve our assignment. We thank all the people for their help directly and indirectly to complete our Project .
