摘要
介绍了SF_6示踪技术测定漏风的原理、仪器装置和测量方法。通过确定SF_6的释放量,取样点与SF_6释放点的间距,运用SF_6连续恒量释放法对某大型煤矿8_上108综放工作面的漏风情况进行定量分析,得出该工作面的漏风来源主要是采空区,漏风量为68.47 m^3/min,漏风率为3.5%,该研究结果为采取针对性的漏风防治措施提供理论依据。
Introduces the principle,instrument and measuring method of air leakage by SF6 tracing technique.The air leakage was analyzed quantitatively in 8上 108 fully mechanized caving face with the method of continuous and constant quantitative releasing of SF6,of sampling points and its space between each point,the results provide a theoretical basis for taking targeted measures to prevent and control air leakage.
