摘要
通过实验室实验的方法来分析煤中水分含量对瓦斯放散初速度的影响规律。实验结果表明,注水对瓦斯放散初速度起到了明显的抑制效应,煤中水分含量与瓦斯放散初速度符合对数函数关系,当煤中水分含量在1.4%~7.9%时对瓦斯放散初速度的影响最大,当煤中水分含量在大于7.9%时,对瓦斯放散初速度的影响逐渐变小,实验结果对现场进行煤层注水具有一定的参考价值。
The influence law that water content in coal to gas diffuse initial velocity was studied by experimental method. The experi- mental results showed that gas diffuse initial velocity was restrained obviously by water injection, the function relation between water content and gas diffuse initial velocity was logarithmic function, when water content was 1.4% - 7.9%, the influence was the maxi- mal to gas diffuse initial velocity, when water content more than about 7.9%, the influence that to gas diffuse initial velocity became smaller and smaller, the experimental results referencing for practical.
