5、　　　　　　　采煤作业规程　-25-　　　　　　　　二、概　　　　况工作面位置19101工作面距位于车场大巷下山左翼,井田西翼，采用走向长壁式开采，走向长为370米，工作面长为110米,方位NE27°,工作面采用单体液压支柱,煤厚2.8米,直接顶板为碳质页岩,中等稳定,底板为碳质泥岩,膨涨系数较大,在回采及放顶工程中应注意钻底现象。回采范围内外的采掘关系和影响19101运输巷和回风巷巷道布置属新开采区域，无旧巷，无采空影响，倾斜长度为110米，离边界有370米左右。在掘进巷道时没有发生过煤与瓦斯突出，即工作面发生煤与瓦斯突出倾向不大。然而工作面在断层之间

6、顶板特别破碎，在回采过程中顶板不好管理。九号煤层上覆岩层为细砂岩和页岩、泥岩，属隔水层岩层，无采空水。九号煤层上覆岩石近距离无厚层灰岩，所以无溶洞水患；　　　　　　　　采煤作业规程　-25-　　　　　　　　三、地　　质回采工作面范围煤层赋存情况煤层情况煤层结构结构致密，节理不发育。综合柱状图柱状厚度（m）文字说明厚度最大2.8米最小2.4米平均2.6米黑色粉沙岩节理发育。倾角最大12度最小6度平均9度炭质泥岩，随采随垮。品种：优质无烟煤硬度：煤均厚2.5m煤层生产能力煤的物理和化学性质黑色块状，腊状光泽，贝壳状断口，容重1.3-1.8，比重1.35-1.

7、9，性小、导电高、导热大、耐热差。灰白色泥岩干燥时较硬遇水变软。顶底板岩石性质岩　性　描　述厚度（m）强度顶板伪顶煤层上有0.6~1.5m伪顶属高炭质泥岩，伪顶上为黑色粉沙岩。0.6~1.5直接顶直接顶岩石节理非常发育，属次生构造，垮落成碎块状。5~154~6老顶石灰岩，块状不易垮落。10~30底板底板属灰色泥岩，遇水变软。2~50.2~0.4　　　　　　　　采煤作业规程　-25-　　　　　　　　地质构造及水文地质煤层沼气、二氧化碳含量及突出危险倾向性开采九号煤层是属于煤层群中一层，上距8号煤层14m左右，下距13号煤层12m，九号煤层厚，但瓦斯含量大，

8、相对瓦斯涌出量为64m3/t，绝对瓦斯涌出量为12m3/min。并有煤与瓦斯突出
