semi mechanised equipment for yayu coal mining

Key technologies and equipment for a fully mechanized top, In order to achieve safe and efficient coal extraction in ultra-thick coal seams with thicknesses ranging from 14 to 20 m, the authors propose a fully mechanized large mining height longwall top-coal caving mining method (thereafter LLTCC mining method), developed a full range of technologies and equipment for a LLTCC mining operation
