新店东井田水文地质分析及涌水量预测

新店东井田构造复杂、断层多且落差大,破坏了其原有的水文单元,使得大气降水、地表水、地下水联系的更加紧密。根据地质资料分析,本区先期地段内主要断层均切割至二叠系茅口组,缩短了煤层与二叠系茅口组的间距,使得更易发生茅口组突水。

HUDROGEOLOGIC ANALYSIS AND WATER MAKE PREDICTION OF EASTERN XINDIAN FIELD

Structure in eastern Xindian field is complex with high drop height, which destroys its＇ original hydrogeologic unit and makes the relationship of atmospheric water, surface water and underground water more closely. According to the geologic information, the main fault cutting to Permian System Maokou formation shortens the distance between coal bed and Permian System Maokou formation, which makes the Maokou formation more likely happen water invasion.
