| 摘 要： | 为有效控制工作面尤其是上隅角瓦斯浓度,防止瓦斯事故的发生,结合山西沁新煤矿低透气性煤层开采实际情况,在分析"U"型通风和"Y"型通风采空区空气流场特性的基础上,提出了基于沿空留巷的"Y"型通风、采空区埋管抽采和卸压区高位钻孔抽采相结合的瓦斯综合治理技术。现场监测结果表明,该技术可以有效控制工作面和上隅角瓦斯浓度。 |
| 关 键 词： | 沿空留巷 低透气性 瓦斯 “Y”型通风 卸压抽采 采空区埋管 高位钻孔 |

| Abstract: | In order to effectively control the gas concentration in working face and upper corner and to prevent the occurrence of gas accidents,combining with the practical situation of low air permeability coal seam of Shanxi Qinxin coal mine,on the basis of analyzing the air flow field characteristics of " U" model and " Y" model ventilation in gob,comprehensive measures of gas control based on gob-side entry retaining of the combination of " Y" model ventilation,buried tubes extracting in gob and high level borehole extracting in pressure released area are proposed.The field monitoring results show that the The technology can effectively control the gas concentration in working face and upper corner. |
| Keywords: | gob - side entry retaining low permeability gas 'Y' model ventilation drainage in pressure releasing area buried tube in gob high level borehole |
