    Experimental Determination of Compressive, Pulling and Torsional Resistance of Mudcakes using a Triple Action Load Cell Assembly

    By Md. Amanullah

    A novel triple action load cell assembly (LCA) was developed to determine three index parameters reflecting compressive, tensile and shear characteristics of mudcakes. The results indicate that the te

    A few remarks on storage of low temperature materials in rock caverns

    By N. Kinoshita, Y. Inada

    The authors have proposed and discussed storage of low temperature materials such as LNG, LPG and frozen food in rock caverns. In this case, as the rock mass around the caverns will receive effects of

    Assessment of mass modulus of a weathered argillaceous rock

    By Chris M. Haberfield, Neil D. Benson

    The assessment of overall modulus (or stiffness) of a fractured weak to moderately strong rock mass is a key parameter in the design of civil engineering works in these materials. It also provides th

    Applications of seismic hazard assessment methods in mines

    By G. van Aswegen

    Large structures in mines (faults, dykes, pillars, abutments) fail when the load exceeds the strength. If the loading system stiffness (LSS, also referred to as the ‘local mine stiffness’) is lower th
