To better understand the thermodynamic process of the compressed air in the underground cavern and the response of the surrounding rock during air charging and discharging phases, a small-scale pilot cavern with concrete liner and fiber-reinforced plastic (FRP) sealing layer was constructed in China.Introduction. Application of mechanical excavators for rock excavation in both civil construction and mining engineering fields has increased significantly in recent years, and small-scale (core cutting) and full-scale laboratory rock cutting tests have emerged as necessities to provide basic data for machine selection, design and performance prediction for a given rock formation [1], [2], [3 ...Correlative study of linear small and full-scale rock cutting tests to ...The chisel picks are usually the main cutting tools in small-scale testing facilities, but they are not commonly used in mechanical excavators. Use of such small-scale tool makes it easier and more convenient to carry out basic study on cutting mechanism and correlating the cuttability with rock properties because of their geometrical simplicity.Use of rock microscale properties for introducing a cuttability index ...احصل على السعر
Small-scale rock cutting test has been developed for the purpose of measuring direct cuttability of a given rock. Available in the Istanbul Technical University is a 10-ton shaping machine used for the small-scale rock cutting tests. This cutting test is discussed in detail in [12], [13], [14]. It is suggested as a standard laboratory rock ...Based on the point clouds collected by a portable laser scanner in the laboratory, 13 small-scale rock joint specimens with different roughness levels were used to assess the effect of roughness level on the selection of the appropriate sampling interval. The results demonstrated that the appropriate sampling interval decreased with the ...Estimation of the appropriate sampling interval for rock joints ...احصل على السعر
