Off-Site and Reverse Uncovering Coal Technology about Outburst Coal Seams Group

Abstract:

In view of the condition of driving roadway in the West Wing mining area in Pan Yidong mine: the -805m jitty and belt conveyor uphill would meet within the coal seams group, and the coal seams group will be opened successively at the two locations. According to uncovering coal difficulty, the method of off-site and reverse uncovering coal to be used to open the coal seams group. At first, opening the coal group in -805m jitty, and then excavating respectively coal seams group up or down in the opposite direction, finally the uncovering coal is finished. One-fourth times was reduced compared to the traditional plan of uncovering coal, achieving a win-win of good economic and security benefits.
