【摘要】：井下直接测定煤层瓦斯含量时,常出现煤样温度过高、瓦斯放散量过多导致损失量的推算不准确,使煤层瓦斯含量的测值出现偏差。基于0℃以上的常温时煤对瓦斯的吸附能力随温度降低而增强的性质,提出冷冻取煤样方法,减少吸附瓦斯的损失量,使瓦斯含量的测值更准确。通过实验探究了低温下温度对煤的瓦斯吸附能力的影响,从理论上证明该方法可行。
[Abstract]:When directly measuring the gas content in coal seam, the temperature of coal sample is too high, and the calculation of loss amount is inaccurate, which leads to the deviation of the measurement value of gas content in coal seam. Based on the property that the adsorption ability of coal to gas increases with the decrease of temperature at room temperature above 0 鈩，
