Abstract Base on applications of its research and achievements on SF_6 single element tracing technology, the author introduced the application of SF_6 two element tracing technology to measure and monitor the ventilation leakage in a complicated goaf. An application of SF_6 - CF_2 CLBr two element gas to measure the ventilation leakage in a complicated goaf was a successful trial in an underground coal mine. It was first to select SF_6, CF_2 CLBr as optimum two element gas with SP-2308 Gas Spectrum Meter, electric catcher and analyzer, and a 5A0 column sieve of a molecular sieve. A high pure nitrogen with a content of 99.999 % was used for the loading gas of the electric catcher and analyzer. A flow of the loading gas was best in 40 ml/min. A column temperature was 70 °C. When a room temperature is 28.5 °C, an analysis sensitivity of the analyzer can be increased. With the application of this technology in a underground coal mine in Huainan, the result shown that this technology is feasible to measure the ventilation leakage in the complicated goaf. 作者根据自己多年应用ＳＦ６单元示踪技术的科研实践，提出应用双元示踪技术检测复杂采空区的漏风。在实验室应用色谱法优选出ＳＦ６、ＣＦ２ＣｌＢｒ双元示踪气体，并在淮南某矿井下首次应用ＳＦ６－ＣＦ２ＣｌＢｒ双元示踪气体成功的检测了复杂采空区的漏风。 The paper,to counter the air leakage in the complicated gob,puts forward the air leakage detection by potential e nergy measurement and tracing technique.It takes the gob around a f ully mechanized face as an example and expounds the use process and method of this tech-nology.This technology is advantageous to the improvement of scientific and accurate detection o f the air leakage in the compli-cated gob. 针对煤矿井下采空区的复杂漏风关系,提出了采用能位测定与示踪技术联合检测采空区漏风,并以某矿一综采工作面周围采空区为例,阐述了该技术的使用过程和方法,该技术有利于提高复杂采空区漏风检测的科学性和准确性,避免盲目性。 According to previous data,there are many old holes or lane ways under the target area,but it is difficult to make clear their scale,configuration,depth and so on.We have mainly used high density electrical technique combined with high precise GPS survey and shallow drill holes.Different electrode spacing has been determined by different cavern type.17 survey lines and 1 140 points in the complicated areas have been finished.In the end,120 electrical anomalies have been discovered.With geological properties... According to previous data,there are many old holes or lane ways under the target area,but it is difficult to make clear their scale,configuration,depth and so on.We have mainly used high density electrical technique combined with high precise GPS survey and shallow drill holes.Different electrode spacing has been determined by different cavern type.17 survey lines and 1 140 points in the complicated areas have been finished.In the end,120 electrical anomalies have been discovered.With geological properties of the area and special shape of anomalies,we have predicte the anomalies of possible cavities and comparatively compacted rocks.The first 19 drills have validated that 15 anomalies are old cavities which have obvious off-drill rod or leak slurry,4 anomalies are relatively compacted limestone.The practice demonstrates that high density electrical technique could precisely predict the space distribution characteristics of complicated underground cavities,and is worth to be applied further. 目标勘查区的深部可能存在多期、多类型、多开采对象的古采硐,难以通过地表调查和常规的技术方法准确搞清其规模、形态、埋深等重要参数.本文采用高密度电法,结合厘米级高精度GPS测量和浅部钻探技术,针对不同类型的洞窟,选用不同的电极距,在复杂采空区地表布设了17条测线,完成了1 140个测点,共圈出120个电性异常.结合测区地质情况和异常的特殊形态,预测了可能为古采硐或相对致密岩石的物探异常.经首批19个钻孔验证,确认15个异常属于发生明显掉钻或漏浆现象的古采硐(陷落坑?),4个异常是较为致密的石灰岩.实践证明,采用高密度电法能够高精度预测地下复杂采空区的空间分布特征.
