·Establishing an Optimized Mine layout The way an underground mine is designed is a key factor for long term successful operation Put simply the easier it is to extract the ore quickly and safely the more productive and profitable the mine will be All mines are unique and nowhere is this more apparent than in the mine layout In the
To reduce layout design time analog layout designers prefer referring to legacy designs and layouts rather than starting from scratch or thoroughly applying placement and routing tools because legacy layouts contain pretty much design expertise Therefore this paper presents the first knowledge based layout synthesis methodology to generate new layouts by integrating
·The layout schemes that differed from the conventional working face layout of the protected seam and in particular envisaged the same layout of the protective and protected seams were implemented being in concert with some field practice Wang et al 2020 Zhang et al 2018a This study proved the latter scheme feasibility intuitively and
