| 摘 要： | 采用示踪技术对Y型通风试验工作面采空区漏风进行了现场检测,估算了采空区漏风风速,研究了漏风分布特点。研究发现:试验工作面采空区漏风范围较广,漏风风速与工作面位置之间呈负指数关系;在距离工作面50m范围内,漏风风速为0.033～0.043m/s;距离工作面200m以远,采空区漏风风速平均为0.018m/s;距离工作面50—200m是漏风过渡区。 |

| Abstract: | The tracing technology was applied to the site detection of the air leakage in the goaf of the Y type ventilation trial coal mining face.The paper estimated the air leakage viscosity of the goaf and studied the air leakage distribution features.The study showed that air leakage scope of the goaf for the trial mining was wide and there was a minus exponent relationship between the leakage air viscosity and the mining face location.Within a distance of 50 m to the coal mining face,the leakage air viscosity wa... |
