Justification of efficient options of fully-mechanized extraction of pitch coal at Kuang Khan Mine

Abstract

Currently, the Vinacomin company actively mechanizes coal mining processes, developing process solutions for coal mining in complicated geological conditions. In accordance with the development plan, "Quang Khan" underground mine is to increase production to 1.5 million tons at annual average increase of 140-150 kt. To achieve this goal, the Quang Khan mine should extract coal reserves in thin seams and inclined seams of medium thickness. Results of the research for selection of the process flow sheet for mechanization of extracting pitch coal of medium thickness in mining and geological conditions of the Quang Khan mine in the Quang Ninh basin of Vietnam are presented.
