义桥煤矿含煤地层对比及煤质特征分析

为了研究义桥煤矿含煤地层对比及煤质特征,综合利用钻探、地震解释、测井及煤质化验成果资料。研究表明标志层、沉积特征、地震解释进行煤岩层对比可靠,3上煤层为局部可采的不稳定中厚煤层,煤类为气煤;3下煤层为大部可采的较稳定厚煤层,煤类为气煤、1/3焦煤;16煤层为局部可采的不稳定薄煤层,煤类为气煤、1/3焦煤。

Analysis of Coal-bearing Formation and Coal Quality Characteristics in Yiqiao Coal Mine

In order to study the coal-bearing strata contrast and coal quality characteristics of Yiqiao Coal Mine,the results of drilling,seismic interpretation,logging and coal quality test are comprehensively used.The research shows that the coal seam of the mark layer,sedimentary characteristic and seismic explanation is reliable.The 3 upper coal seam is a locally recoverable unstable medium-thick coal seam,and the coal type is gas coal;the 3 lower coal seam is a mostly recoverable thicker coal seam,the coal type is gas coal,a third of coking coal;the No.16 coal seam is a locally recoverable unstable thin coal seam,and the coal type is gas coal,a third of coking coal.
