对南桐煤田的青年矿、鱼田堡矿和南桐矿煤样在不同应力状态下及不同电场下的渗透率进行了研究，得出了煤渗透率与有效应力和电场强度之间的关系。对了解煤的渗透特性、瓦斯涌出量预测具有一定参考价值。 The permeability of coal samples of Qingnian Mine, Yuetabao Mine and Nantong Mine in Nantong Coalfield under different stress states and different electric fields was studied, and the relationship between coal permeability and effective stress and electric field strength was obtained . To understand the permeability characteristics of coal, gas emission prediction has some reference value.
