    Mine Seals ? A Rational Base for Design and Construction

    By Kot Unrug

    Mine seals are necessary in nearly every mine to isolate mined-out areas from the ventilation network. There is a large number of seals in active mines and that number continually increases as the de

    Alleviation of Rock Bursts by Identifying Burst-Prone Mine Workings

    By S. Paul Singh

    Rock burst is one of the most serious mining hazards, adversely affecting the safety, economy and productivity of mines. It is a sudden manifestation of the release of strain energy stored in the rock

    Analytical Solutions of Hard Roof’s Bending Moment, Deflection, and Energy under Front Abutment Pressure before Periodic Weighting

    By Yun Zhang, Haijun Jiang, Shenggen Cao, Chen Wang

    The distribution of front abutment pressure is closely related to the force, deformation and energy distribution of hard roof before periodic weighting. So it is necessary to carry out research on the
