为准确判断冻结壁交圈情况,进行了冻结器纵向测温,获得了东峰煤矿中后期进风井冻结孔各冻结器纵向温度分布情况,发现该井筒冻结壁发展整体比较均匀,结合井筒灌水情况,为冻结壁交圈情况判定提供了依据。
In order to accurately judge the circumstance of frozen wall cross-section, longitudinal temperature measurement of the freezer was carried out and the longitudinal temperature distribution of each freezer in the middle and late stage of the intake shaft of Dongfeng Coal Mine was obtained. The development of the freezing wall in this well bore is more uniform, The situation provides the basis for the determination of the frozen circle of circles.
