6、軌道上山,東為實體,北臨杏園煤礦采空區(qū)。第二節(jié)煤(巖)層賦存特征一、煤層及頂?shù)装灞?-1煤層及頂?shù)装迩闆r煤層情況煤層平均厚度(m)7.5煤層結(jié)構(gòu)簡單煤層傾角(°)0~5煤層名稱及性狀:4-1號煤組以暗煤以主,具鏡煤及亮煤,瀝青光澤,棱角狀-貝殼狀斷口,條帶結(jié)構(gòu),層狀構(gòu)造,水平層理,外生裂隙發(fā)育,比重大,質(zhì)硬。4-1號煤上部含暗煤成分多,中下部則以亮煤成分居多。40頂?shù)装迩闆r名稱巖石類別厚度(m)巖性特征頂板粗砂巖、泥巖、砂質(zhì)泥巖0.50-12.70細砂巖,中細砂巖;膠結(jié)較好比較堅硬直接底粉砂巖1.17-3.24泥巖中砂巖,富動植物化石老底粗、細、粉砂巖 5.0—7.8灰白色中粗粒砂巖,較堅硬
7、。二、影響掘進的其它因素其它地質(zhì)情況瓦斯掘進期間最大瓦斯涌出量為0.55m3/min。瓦斯相對涌出為1.52m3/t,絕對瓦斯涌出量為0.95m3/min二氧化碳二氧化碳相對涌出量為2.53m3/t,絕對涌出量為1.58m3/min煤塵具爆炸危險性。煤層自燃煤層具有自燃傾向性,屬自燃煤層,自燃等級為Ⅱ級地溫屬地溫正常區(qū)地壓屬地壓正常區(qū)第三節(jié)地質(zhì)構(gòu)造本區(qū)域位于寧武煤田北部平朔礦區(qū),寧武煤田的東緣及東北緣太古界交
