Abstract

Spontaneous combustion and gas control technology at fully mechanized working surface during withdrawing support period is a major issue in easy spontaneous combustion seam and gas mine.Through selecting the method of closed nitrogen injection to withdrawal support and taking comprehensive fire prevention and gas control technology, coal spontaneous combustion can be effectively prevented and controlled, which prevents gas overrun and ensures safety production.
- fully mechanized coal face,
- spontaneous combustion,
- gas control technology
