针对目前矿井井下联孔存在的不足,研制了一种新型联孔装置及相关配件。通过实验室气密性测试,实现井下联孔可变可调,在3个试验矿井进行现场应用,表明新型联孔装置大幅度提高了系统气密性,操作简便,具有优越的现场适用性。
Aiming at the shortcomings of the existing underground mine coalescence hole, a new type of cross-hole device and related accessories have been developed. Through laboratory gas tightness test, the downhole borehole can be adjusted variably and can be field-applied in 3 pilot mines. It shows that the new cross borehole device greatly improves the airtightness of the system, is simple to operate and has excellent field applicability.
