摘要
根据钻孔和煤矿地质资料,采用标志层法、古生物法、岩煤组合特征,结合煤质特征及物性特征,对涟邵煤田测水煤系主要可采煤层进行对比。涟邵煤田3、5号可采煤层位于测水组下段,两煤层之间发育一层层位稳定、厚约11m的1号石英砂岩,该层砂岩为3煤层底板、5煤层顶板,全区发育;5煤底板发育B层菱铁矿结核。1号石英砂岩和B层菱铁矿结核均为含煤段主要标志层,对比可靠。
According to the coal mine drilling and geological data,using sign-law,paleontology law,rock coal characteristics and combining with coal quality and physical characteristics,the main mining coal seam in Lianshao coalfield measuring water coal system are compared.Lianshao coalfield 3#,5# coal seam are under the water group,between two layers grow a stabl,quartz sandstone with 11 m thickness.The sandstone layer,are 3# coal floor,5# seam roof and develop all area.5# coal-floor grows B-siderite tuberculosis.1# quartz sandstone and B-siderite tuberculosis are main mark coal seam,and comparison is reiable.
