Predicting the Relationship Between System Vibration With Rock Brittleness Indexes in Rock Sawing Process

Abstract

The system vibration is a very significant measure of the sawing performance, because it indicates the amount of energy required to saw the rock. The maintenance cost of system is also dependant on system vibration. A few increases in system vibration cause a huge increase in the maintenance cost of the system. In this paper, the vibration of system in terms of RMSa was investigated and models for estimation of vibration by means of rock brittleness indexes and operational specifications were designed via statistical models and multiple curvilinear regression analysis. In this study, the relationships between rock brittleness indexes and operational specifications were investigated by regression analysis in statistical package for social science (SPSS) and the results of determination coefficients have been presented. In the second part, the diagrams show that a point lying on the line indicates an exact estimation. In the plot for model, the points are scattered uniformly about the diagonal line, suggesting that the models are good. It is very useful to evaluate the vibration of system and select the suitable operational characteristics by only some mechanical properties of rock.Keywords: system vibration, brittleness indexes, sawing process, statistical analysis Drgania układu uważane są za miernik wydajności procesu urabiania, ponieważ pokazują ilość energii niezbędnej do urabiania skały. Od poziomu drgań zależą także koszty eksploatacji systemu. Nieznaczny nawet wzrost poziomu drgań prowadzi do znacznego zwiększenia kosztów eksploatacyjnych urządzenia. W pracy tej przeprowadzono analizę drgań (ich wartości skutecznych) i opracowano model estymacji poziomu drgań w oparciu o współczynnik kruchości skał i parametry eksploatacyjne urządzenia. W pracy wykorzystano modele statystyczne i wielokrotną analizę metodą regresji krzywoliniowej. W pracy obecnej związek pomiędzy współczynnikiem kruchości skał a parametrami eksploatacyjnymi urządzenia badano z wykorzystaniem analizy metodą regresji dostępnej w statystycznym pakiecie oprogramowania dla nauk

Constraining Shear Strength of Fault Damage Zone Using Geodetic Data and Numerical Simulation

“…However, the mechanical properties of rock materials are closely related to lithology, confining pressures (McBeck et al, 2023;Wang et al, 2020), brittleness (Altındağ & Güney, 2010;Hucka & Das, 1974;Mikaeil et al, 2011;Wang et al, 2014), fluid saturation (Verwer et al, 2010;Yoshida et al, 2016), and pore conditions (e.g., porosity, permeability ;Fossen, 2016;Gu et al, 2016;Kaproth et al, 2016;X. Li et al, 2017).…”

Li et al., 2017). To mitigate the potential impact of various factors on the strength estimations, our strengths are inferred from the overlapping peak shear stress in the contiguous pairs of surface rupture and non‐rupture segments (e.g., R1‐N1‐R2), which has equivalent space scales (lengths of 2–5 km) and passed through Permian‐Triassic sandstone.…”

“…In another study, Mikaeil et al investigated the relationship between the amperage draw of a disc cutting machine and the brittle-Rudarsko-geološko-naftni zbornik i autori (The Mining-Geology-Petroleum Engineering Bulletin and the authors) ©, 2022, pp. 133-148, DOI: 10.17794/rgn.2022.5.11 ness of rock samples (Mikaeil et al, 2011c). Ataei et al studied the cutability of dimension rocks from the energy consumption perspective and the relationship between mechanical rock characteristics and the operational features of the cutting machine (Ataei, et al, 2012a).…”
