以型煤为实验样品,通过对煤样在不同有效应力、瓦斯压力条件下,进行间歇注热的解吸实验,并对注热前后的煤样进行孔隙、裂隙的微观扫描,研究温度、间歇注热对煤层气解吸量及孔隙、裂隙发育的影响。 Taking briquette as the experimental sample, desorption experiments of intermittent injection of coal samples under different effective stress and gas pressure conditions were carried out. Microscopic scanning of pores and fissures was performed on the coal samples before and after the injection. The effects of temperature, intermittent injection Effect of heat on desorption of coalbed gas and pore and fissure development.
