The content of coalbed methane (CBM) is an important parameter that affects the performance coal extraction and safety mines. importance this especially more pronounced when using direct method to determine CBM content, in which measuring accuracy lost gas results. loss affected by pressure exposure time. In article, influence time on estimation results rate was investigated. Moreover, sampling interval observation kinetic model simulating desorption process analyzed. obtained demonstrated...
Coal and gas outburst is the mechanical damage behavior of gas-containing coal in a complex environment. In this paper, established experimental system used to carry out hammer experiments on adsorption different gases under pressures analyze mass distribution surface area characteristics samples each particle size interval after samples. The energy crushing process was analyzed by using specific work crushing, newly generated added per unit energy, energy. results show that effect during...
To study the characteristics of effect degassing vacuum degree on gas adsorption performance coal, experiments were performed raw and particle coal under different conditions. The is measured in real time during whole experiment. experimental results demonstrate that higher degree, greater capacity growth rate capacity. With elevation free energy pore surface body increases conditions ability to adsorb increases, which shows rises. By comparing difference identical vacuum, it can be derived...
