| Abstract: | Based on the spontaneous combustion tendency and low permeability close and thin of coal seam's mining face of gas emission rule in high-content methane mine,the article research that aiming at this seam conditions,for achieving high yield and high efficiency coal mine,use ULtype ventilation mode.Research shows that:compared with the traditional way of mine ventilation,the newULtype ventilation mode effectively solve the difficult problems that working plane the top corner gas overrun,coal spontaneous combu... |
