Evaluation of Disc Cutter Performance in Rock Cutting Process Using 3D Finite Element Method
Today, numerical simulation can be used as a suitable tool to measure large quantities that are very expensive and, in some cases, impossible to measure. One of the important issues in predicting rock mass boreability in excavation with full face tunnel boring machines is estimating the discchr('39')s forces for rock cutting. For this purpose, the linear cutting test is employed. However, limi...
متن کاملCrystal chemistry of hydration in aluminous orthopyroxene
Hydrogen incorporation in aluminous orthopyroxene may control the generation of melt and dominate the seismic properties at the base of the Earth’s lithosphere. To clarify the substitution mechanism of H, we have synthesized, characterized, and refi ned the crystal structure of this potentially signifi cant variant of orthopyroxene. The experimentally produced crystals are small needles up to a...
متن کاملEvaluation of the Cyanidation Leaching of Gold in a Waste Rock Ore
Samples of the waste rock obtained from Marofengin South Africa ground 60, 70 and 80% passing 75µm were leached with cyanide in bottle roll tests. The results obtained showed that the percentage gold dissolution depends more on the ore size consists than on the cyanide concentration with the highest average dissolution rates of 88.75, 94.34 and 95.90% found at 600, 500 and 500 ppm, for 60, ...
متن کاملAssessment of abrasiveness for research of rock cutting
Rock abrasiveness is ability of rock to wear down the working tool during the mutual interaction between the working indentor and the rock in the mechanical rock cutting process. The cutting indentor is worn down during the interaction, which changes its geometric dimensions causing the enlargement of a contact area between the tool and the rock surface. The changes in these dimensions conseque...
متن کاملStudy on Creep Characteristics of Cemented Waste Rock Backfills
Slip instability and tensor instability are two kinds of failure modes of cemented waste rock backfills. In order to simulate the creep characteristics of cemented waste rock backfills, PFC was carried out. The results show that: rocks inside the models will have displacement under load. The expansion is caused by large lateral displacement of the rocks. A non-stationary creep model of cemented...
