摘要 利用焦作九里山煤矿 70个钻孔资料编制的二1 煤层等厚线图 ,发现煤层呈厚薄相间的条带状 ,大致呈南北或北北西向展布 ,平均厚度 5 35m ,系一厚煤层。影响二1 煤层厚度变化的因素主要为河流后生冲刷 ,其次为古地形和构造等。煤层厚度变化影响了采掘部署和生产计划的实施 ,增加了巷道掘进量和探测煤层厚度工作量 。 The authors have found on the isopach map of coal bed Ⅱ 1 drawed up by the use of 70 boreholes data the followin some facts:the coal bed presents the banded shape with alternation of thick and thin,generally is the northsouth of north-northwest direction distribution,average 5.35m thick and belongs to the thick coal bed. The main factors which influence on the changes of the thickness of the coal bed Ⅱ 1 are the fluvial deuterogenic scouring,the paleotopography,the structure,etc. The changes of coal bed thickness can affect the mining deployment and completion of productive plan,increase the driving of headings and exploration work of the thickness of coal bed,decrease the recovery ratio of coal resources and so on.
