摘 要:为实现综采面瓦斯灾害的有效防治,以斜沟矿18112综采面为工程背景,对比研究了U型通风和U+I型通风采空区瓦斯运移规律。基于此,提出通风方式优化、上隅角设置多重风幛以及喷雾装置、降低工作面推进速度等综采面瓦斯治理措施。研究表明,U+I型通风更有利于降低采空区漏风和瓦斯浓度,工作面风速的增加可降低回风巷瓦斯浓度。In order to realize the effective prevention and control of gas disaster in fully mechanized mining face,taking the 18112 fully mechanized mining face of Xiegou Coal Mine as the engineering background,the law of gas migration in goaf with U-type ventilation and U+I type ventilation is compared and studied.Based on this,this paper puts forward some gas control measures in fully mechanized mining face,such as optimizing ventilation mode,setting multiple air damper in upper corner,spraying device,reducing advancing speed of working face and so on.The study shows that the U+I type ventilation is more beneficial to reduce the air leakage and gas concentration in the goaf,and the increase of the air speed in the working face can reduce the gas concentration in the return air roadway.
