河南火店南煤勘查区煤岩层对比

Correlation of coal and rock seams of coal exploratory Area in Southern Huodian,Xiayi County,Henan

在煤炭地质勘查及煤矿生产勘探中,为了对各勘查工程所揭露的煤层进行统一的编号,并准确地对地层和煤段进行划分,以便查明区内各可采煤层的赋存状况,并对其进行正确的分析与评价,通常要开展煤岩层对比工作。煤岩层对比的方法有多种,一般会选择若干种方法进行综合对比。文章通过主要煤层和标志层及其层间距、煤岩层组合特征、主要煤层和标志层物性特征、主要煤层煤质特征等多种方法,对夏邑县火店南煤勘查区煤岩层进行了系统的对比研究,对该区及周边地区进一步开展煤炭地质勘查与生产勘探工作具有参考意义。

In coal geological prospecting and coal mine production prospecting,in order to unify the serial number of each coal seam exposed by each exploration engineering,and accurate determination of strata and group of coal seam,so that ascertain the occurrence of each workable coal seam in the area,and make correct analysis and evaluation of each workable coal seam,it is usually necessary to carry out correlation of coal and rock seams.There are many methods for correlation of coal and rock seams.Generally,several methods are selected for comprehensive comparison.This paper makes a systematic comparative study the coal and rock seams of coal exploratory area in Southern Huodian of Xiayi County by means of the main coal seams and marker beds and their spacing、coal-rock combination characteristics、physical property characteristic of the main coal seams and marker beds、coal quality characteristics of the main coal seams and the like multiple correlations.It has important guiding significance for further coal geological prospecting and coal mine production prospecting in this area and its surrounding areas.
