五凤井田龙潭组含煤层数多,厚度变化较大,根据井田钻孔地质资料,采用标志层法、古生物法,结合物性特征及煤质特征等对井田主要可采煤层进行对比。该井田6号煤位于龙潭组顶部,上距龙潭组顶部灰岩标志层6m,±常分叉为6上、6中、6下三层,6中煤层平均厚度>2m,为全区最厚,且唯一可采煤层,对比可靠;26号煤位于龙潭组中段底部,结构简单,无夹石,其直接顶板为高伽马异常,与上下相邻煤层区别明显;33号煤位于龙潭组下段,是井田内唯一一层大可部分可采的高硫煤,易于对比。
The Longtan Formation in Wufeng Mine Field has many coal layers and great thickness variations. Based on the borehole geological data of the field, the main recoverable coal seams in the mine field are compared by using the marker layer method, the paleontology method, the physical property characteristics and the coal quality characteristics. The mine No. 6 coal mine is located at the top of Longtan Formation and is 6m above the limestone mark on the top of Longtan Formation, ± 6 on the 6th, 6th and 6th lower. The average thickness of the 6th coal seam is> 2m, No.2 coal is located at the bottom of the middle section of Longtan Formation, with simple structure and no gravel. Its direct roof is characterized by high gamma anomaly, which is obviously different from the adjacent coal layers in the upper and lower sides. Coal No.33 is located in Longtan Formation The next paragraph, is the only layer within the mine can be partially recoverable high-sulfur coal, easy to contrast.
