根据万全煤田褐煤(原煤)平衡水等温吸附实验,计算了褐煤的吸附气含量;根据水溶甲烷实验模拟,估算了煤层中的水溶气;采用比重瓶法和压汞实验,利用马略特定律,推算了褐煤游离气含量。
Based on isothermal absorption test of balanced water of browm coal (raw coal), the adsorption gas content of brown coal is calculated. Based on laboratory simulation of water soluble methane, the water soluble gas in coal seam is estimated. The free gas content of brown coal is estimated by using pycnometer (bottle) method and mercury intrusion method and Mariotte Law.
