Abstract

Qareh Qeshlaq marble quarry as one of the valuable resources of ornamental stones in West Azarbaijan province formed through thermal carbonate springs while its mineral deposit thickness is limited in comparison with surface extension. In the present research, geological and blocky modeling of the marble deposit was carried out in order to develop a production planning for this quarry, identifying the position of single-marketable-block extracted from it and increasing its economical aspects for exploitation. During the study, in addition to preparing a geological and blocky model for the quarry, firstly the optimum dimensions of its extractable single marketable-block were quantified and then through representing the confining surfaces equation of marble strata in the computer, the optimal maximum dimension and the number and exact location of the single marketable-blocks were determined and presented to the operating team. Based on the findings of these studies and according to the existing 83 exploratory boreholes data, it is possible to extract 183 single marketable-block pink marble and 103 single marketable-block malachite both with 1.5 × 2.5 × 2.5 m raw dimensions while only 2 single marketable-block alabaster layer with 1.3 × 2.5 × 2.5 m dimensions. The results also show that with applying extraction consideration, regarding the productivity coefficient of the layers, and removing the gradual color changes zone, the maximum thickness of the single marketable-blocks for the pink marble, malachite, and alabaster will become 1.65, 1.65 and 1.4 m, respectively.
