| Abstract: | Mining working face, especially in the middle and end zone, exist spontaneous combustion safety problems in different degrees, and even cause working face closed due to spontaneous combustion. Taking C13 seam for example, to eliminate safety hazards and ensure safety in production are putting for- ward by using nitrogen-injection system and filling system and adopting the method of drilling nitrogen-injection and filling. |
