Paper Number: ISRM-EUROCK-2014-108
... Abstract Based on experience, measurements and stress analyses, the authors have developed and implemented guidelines for stress control in multiple seam mining layouts. Mining sequence in deep coal areas of EWMC is in descending order. Measurements in the lower seam have confirmed yielding of...

... dimensions. This can result in these pillars triggering damaging seismicity. On some mining operations crush pillar layouts are implemented at 400 meters below surface (mbs).At this shallow depth, pillar crushing is typically not achieved. mining height du Plessis evaluation limit equilibrium...

... newly developed explosive-rock interaction model. Results from the modelling work were used to understand the complex mechanisms at play under fully confined blasting conditions. In addition they helped identify improvements in explosive charge initiation and blasthole layouts to enhance the extent of...

... illustrated the impact of mining depth and pillar size on pillar behaviour. 1 INTRODUCTION During the past four decades, several studies regarding the behaviour of crush pillars were conducted in an attempt to better understand and predict the behaviour of these pillars. Crush pillar layouts nevertheless...
