摘要
煤层割理是影响煤储层渗透率的主要参数之一,铁法矿区煤炭储量丰富,阜新组含煤二十层,各煤层割理的发育程度差异较大,其中以7、12、13等煤层割理最为发育,割理间距0.05～0.4mm,一般无充填物,组合类型以孤立--网状为主。
The coal seam cutting vein is one of the main parameters affecting coal reserves osmosis ratio. Tiefa coal mine has a lot of coal , Fuxin group has twenty levels of coal , and there are many different developments between the coal steams. Among them the seventh, the twelfth and the thirteenth coal steams developed best.The intervals are between 0.05mm and 0.4mm in these parts , there are usually no tampons and the combination types are mainly isolated to net.
