A Pre-Feasibility Study of Limestone Quarry Development for Cement Industry in Cambodia

Abstract:

s: Cambodia is a developing country, and mining sector is just started within the last 10 years. Many mining companies have started to explore and carry out the feasibility study amid the scarcity of geological data and technical code of practices. Therefore, the quarry sector is also considered at the early stage in Cambodia, and it is required a standard quarry planning practice. This paper will present the main concepts of (1) quarry operation, development, and design by using the commercial program Minesight to accommodate the mine planning and scheduling. as the result, 25 million ton of limestone was calculated to be a reserve with production of 1 million ton per year; (2) financial model, consisted of cash flow analysis, net present values (NPV), and the Internal Rate of Return (IRR) are the main point for economics consideration. In this point, 47% of internal rate of return was calculated with the net present values of 21.5 million US Dollar and (3) the environmental impact which involves dust, noise, vibration impacts and mine rehabilitation, will be addressed base on the specific local conditions.
