新生界含水性及其与矿井充水的关系

THE RELATIONSHIP OF WATER CONTENT IN CENOZOIC GROUP TO WATER—CHARGING IN COAL MINES

综合分析了开平煤田的煤系上覆新生界沉积特征和含水性,对其与矿井充水的关系进行了讨论和预测,指出其下部段位的含水性弱,不应因底部有卵砾石层而谈虎色变,而要在勘探时就对其具体沉积特征和含水性做深入研究。

The paper made a comprehensive analysis on the sedimentary characteristics and water content of overlying Cenozoic Group of the coal measure in Kaiping Coal Basin. Their relationship to water—charging in mines was discussed and predicted. It was indicatde that it should make a deep investigation into the sedimentary characteristics and water centent during the exploration phases, and because the water content was low in the lower of the Cenozoic Group, it should not 'turn pale at mere metion of the base gravel bed'.
