| 摘 要： | 型煤的渗透性对研究保护层开采过程被保护层的透气性变化规律有重要作用,为此设计了型煤渗透性测试系统。研究得出型煤在加载过程中型煤透气性变化与正应力之间符合指数函数规律;在卸载过程中型煤透气性与正应力之间符合幂函数规律。同时研究了相同载荷、不同流程、不同渗流压差时,试样渗透性变化规律及流体在人工捣实型煤中的流态。

| Abstract: | The coal briquette penetrability is important in researching the rule of protected stratum penetrability changes during the period of protecting stratum mining.The measurement system about the coal briquette penetrability coefficient has been designed.The exponential function rules of coal briquette penetrability coefficient were found on the coal briquette loading and unloading.The rules of coal briquette penetrability change and gas flowing state were educed under uniform load and different distance and pressure. |
