Moessbauer Spectroscopy for Lunar Resource Assessment: Measurement of Mineralogy and Soil Maturity [PDF]
First-order assessment of lunar soil as a resource includes measurement of its mineralogy and maturity. Soils in which the mineral ilmenite is present in high concentrations are desirable feedstock for the production of oxygen at a lunar base.

Deep Underground Science and Engineering, EarlyView.The influence of gas on the instability and failure of rock–coal–rock combinations is considered. The damage characteristics of gas‐bearing rock–coal–rock combinations under different confining pressures, axial loading rates, and gas are revealed. A constitutive model for gas‐bearing rock–coal–rock damage considering gas is established.

Deep Underground Science and Engineering, EarlyView.Ground‐borne vibrations are a frequent source of environmental problems. A full‐scale experiment is conducted to validate a 3D numerical model in order to analyze the efficiency of three methods of isolation. Trench barriers and wave‐impeding blocks are impractical and expensive methods of isolation, but mass scatters appear to be an efficient ...

Deep Underground Science and Engineering, EarlyView.The present study uses the Modified Mohr‐Coulomb true‐triaxial failure criterion (MMC_TT), which predicts the strength of rock better than the MGC criterion in laboratory true‐triaxial tests to overcome the limitations. Moreover, based on the data from previously published five vertical wells in the Krishna‐Godavari basin (K‐G basin), an empirical ...
