1. Innovative approach to strata reinforcement in coal mines with reference to evaluation cable bolts shear strength

N. Aziz; A. Mirzaghorbanali; G. Yang; S. Khaleghparast; H. Resekh

Volume 9, Issue 3 , Summer 2018, , Pages 703-715


  There is an increasing need to determine accurately the strength properties of tendons for an effective ground control on mines and underground structures as well as on modelling simulations. The strength properties of cables, used as cable bolts, have been evaluated mainly by their ultimate tensile ...  Read More

2. An experimental study of axial load transfer mechanisms of cable bolts using axially split embedment apparatus

A. Mirzaghorbanali; N. Aziz

Volume 8, Issue 2 , Spring 2017, , Pages 131-137


  The load transfer mechanisms of cable bolts differ from those for normal rebar bolts. The cable bolts used in mines are basically steel strands with different constructions depending on the number of wires or elements and the way they are laid. Tendon bolts (rebar and cable) are normally evaluated for ...  Read More

3. Effect of air column in transport canisters on measured gas contents of coal

N. Aziz; A. Mirzaghorbanali

Volume 8, Issue 1 , Winter 2017, , Pages 1-9


  Canister desorption is a widely used technique to measure the gas content of coal. The gas content data, when normalized to volume/weight and multiplied by coal seam mass, is used to estimate the gas in place in an area around the cored hole. However, the gas content and the percentage of each constituent ...  Read More
