In the first phase of the water disaster control project,to seal the water inrush gateway and to drain water from the mine were the main operations and meanwhile,the surface drilling exploration,3D seismic,transient electric:method and other comprehensive means were applied to determine the inrush water channel as the hidden sink hole with good water conductivity.
东庞煤矿在2903工作面下巷掘进时突水被淹,水害治理一期工程中以封堵突水巷道、排水复矿为主,同时采用了地面钻探、三维地震、瞬变电法等综合手段,为确定突水通道为导水良好的隐伏陷落柱,不同探测手段确定的陷落柱截面积相差10倍以上;在二期陷落柱封堵工程中,在一期探查资料的基础上,以钻探资料为约束,以三维地震精细解释为重点,对陷落柱的边界重新进行了解释定位,确定了陷落柱空间形态,经过大量钻探工程验证,地质探查效果良好。
补充资料：传热周边
分子式：
CAS号：
性质：在解决传热问题时所用的当量直径与用于计算压降的形式上虽相同，Ds=4rh；rh=流通面积/润湿周边；但两者的润湿周边定义则有所不同。以套管换热器为例，计算环隙中流体压降时的rh时，润湿周边为πDl+πD2，D1为内管外径，D2为外管内径，而计算传热时，润湿周边则为πDl，并称之为传热周边。
