浅谈澄合矿区义合井田煤层对比

Discussion on the coal seams correlation of Yihe minefield in Chenghe mining area

澄合矿区义合井田位于陕西省渭北石炭二叠纪煤田澄合矿区中深部详查区西部。井田为掩盖式含煤区,参与资源量估算的煤层有3煤层、4煤层、5煤层及10煤层,分别采取沉积旋回法、标志层对比法、煤层特征及地球物理测井物性特征对比等方法对井田内煤层进行了对比,结论比较可靠。

Yihe minefield is located in the western detailed investigation district of Chenghe mining area in Shaanxi Weibei Permo-Carboniferous coalfield,which is concealed coal bearing area.The coal seams of 3#,4#,5#,10#were taken part in the resource estimation.The methods including the sedimentary cycle,marker layer,coal seam property and geophysical logging were carried out for coal seam correlation in the minefield and reliable conclusion was obtained
