摘要
为了验证煤中水含量对瓦斯的吸附与解吸特性的影响,分别对煤样在不同平衡压力条件、不同水含量状态下的瓦斯吸附与解吸进行了实验。实验结果表明,煤对瓦斯的吸附能力随着煤中水含量的增加而减小,实际应用中可近似用水含量对煤吸附瓦斯影响系数进行修正;煤中水含量越大,瓦斯的解吸就越慢,残存瓦斯量越大,水充填在煤样空隙中后对瓦斯的吸附和解吸均有一定抑制作用。
In order to verify the influence law of water content in coal to gas adsorption and desorption characteristics, gas adsorption and desorption experiments were carried out in different equilibrium pressure conditions with different water content in coal. The experiment results show that the gas adsorption capacity decreases with increasing of water content in coal, it could be corrected by use of water content influence coefficient in practical application. With the water content increasing, the gas desorption became slower and the amount of gas remaining was greater. The water filled in the coal gap has inhibitory effect to gas adsorption and desorption.
