Abstract

Predictions of cutting and bead consumption rates of diamond wire cutting machines are major subjects in determining the economics of natural stone quarrying. The main aim of this study is to develop empirical models to predict areal net cutting rate and bead consumption rate of diamond wire cutting machines based on statistical analyses using different physical and mechanical properties of natural stones at macro and micro scales. Firstly, twenty different natural stone quarries in Turkey were visited to collect natural stone samples and record field performance (areal net cutting rate and bead consumption rate) of diamond wire cutting machines. Macro and micro scale tests were applied in the laboratory on twenty-five different natural stone samples of metamorphic and sedimentary origins obtained from the fields. Macro-scale physical and mechanical property tests include density, uniaxial compressive strength, Brazilian tensile strength, Shore scleroscope hardness, and Schmidt hammer hardness. Micro-scale tests include texture coefficient, Knoop microhardness, and mean grain size. Then, simple, multiple linear, and multiple non-linear regression analyses were carried out using the macro and micro scale stone properties and the areal net cutting rate and bead consumption rate. An important feature distinguishing this study from previous ones is the use of micro and macro properties of stones separately and together, as well as the use of a very large number of data with high diversity. Results indicate that the models suggested in this study may be very useful and reliable tools for predicting the areal net cutting rate and bead consumption rate of diamond wire cutting machines.

指导金刚石线切割机切割和切割珠消耗率经验预测的实地和实验室研究
预测金刚石线切割机的切割率和砂珠消耗率是决定天然石材开采经济性的主要课题。本研究的主要目的是利用天然石材在宏观和微观尺度上的不同物理和机械性能,在统计分析的基础上建立经验模型,以预测金刚石线切割机的平均净切割率和砂珠消耗率。首先,考察了土耳其 20 个不同的天然石材采石场,收集天然石材样本并记录金刚石线切割机的现场性能(等面积净切割率和砂珠消耗率)。在实验室中,对从野外采集的 25 种不同的天然石材样品(变质岩和沉积岩)进行了宏观和微观测试。宏观物理和机械性能测试包括密度、单轴抗压强度、巴西抗拉强度、肖氏硬度和施密特锤击硬度。微观尺度测试包括纹理系数、努氏显微硬度和平均粒度。然后,利用宏观和微观尺度的石材属性以及面积净切割率和砂珠消耗率进行简单、多重线性和多重非线性回归分析。本研究有别于以往研究的一个重要特点是分别和同时使用了石材的微观和宏观属性,并使用了大量具有高度多样性的数据。研究结果表明,本研究提出的模型可能是预测金刚石线切割机等高净切割率和砂珠消耗率的非常有用和可靠的工具。

期刊介绍: Engineering geology is defined in the statutes of the IAEG as the science devoted to the investigation, study and solution of engineering and environmental problems which may arise as the result of the interaction between geology and the works or activities of man, as well as of the prediction of and development of measures for the prevention or remediation of geological hazards. Engineering geology embraces: • the applications/implications of the geomorphology, structural geology, and hydrogeological conditions of geological formations; • the characterisation of the mineralogical, physico-geomechanical, chemical and hydraulic properties of all earth materials involved in construction, resource recovery and environmental change; • the assessment of the mechanical and hydrological behaviour of soil and rock masses; • the prediction of changes to the above properties with time; • the determination of the parameters to be considered in the stability analysis of engineering works and earth masses.
