Abstract

Abstract:

By means of drilling, gas chromatograph analysis Yuxing coal mine 1601 face small mines firing old mined-out area inside the airtight site analysis. Shotcrete plugging, reinforcement sealed,drilling grouting effective underground mine fire control technical measures are used. The combustion of 1601 small mines old mined-out area is effectively governed, make small mines combustion effects on already made his mine safety in production is greatly reduced, effectively guide the mine safety production.

Key words: Small mines, Drilling, Grouting
