Second, the use of clustering algorithms made it possible to more accurately identify the cause of equipment failures. Using this approach, the mine learned that a particular portion of the truck fleet was suffering more failures—and that all the trucks in that portion were being used in a part of the mine that had very rough roads.
eliminate outburst risk in coal seams, these methods can hardly help realize the green development trend of coal and CBM co-extraction because they cannot guarantee the current situation of highly mechanized mining. In this study, a three-dimensional coal and CBM co-extraction strategy was proposed. The strategy includes three lev-
