我们所建成的几对矿井及其它一些矿井的井筒实际涌水量和利用勘探阶段提供的参数预计的水量,往往差别很大。例如:芦沟矿竖井筒,按原参数预计只有40米~3/时,建井期揭露的水量达到200米~3/时,比预计大了4倍。河北和山东等地的一些矿井,也出现水量偏大或偏小的现象。针对这一问题, The actual volume of water in the wellbore of the several pairs of mines and other mines we built and the amount of water projected using the parameters provided during the exploration phase often vary widely. For example, the shaft of the Lugou Mine is estimated to be only 40m3 / h according to the original parameters, and the water amount disclosed in the well-construction period reaches 200m3 / h, which is 4 times larger than the expected. Some mines in Hebei and Shandong have also experienced large or small quantities of water. To solve this problem,
