应用扫描电子显微镜观测瓦斯突出煤层,国内外都有过报导。英国在研究南威尔士煤田时指出,突出危险的无烟煤中,在电子显微镜下可以看见有直径小于5微米的“粒束”扁豆形结核,其构造有粉碎层,在各粉碎层之间有光滑的擦面,在滑动擦面上有大量的微裂纹。(日)粟原一雄等用扫描电镜观察到突出危险煤有熔融的痕迹,并认为这是由于火山侵入引起煤二次加热的结果。我国抚顺煤研所电镜室也于1978年发表过“应用扫描电子显微镜对煤质微孔结构的观测”的文章。
Observation of gas outburst by scanning electron microscope has been reported both at home and abroad. In the study of the South Wales coalfield, the United Kingdom pointed out that in the most dangerous coal anthracites, “grain-bundle” lentil tubers less than 5 microns in diameter were visible under the electron microscope and were constructed with a crushed layer with smooth between the crushed layers Wipe the surface, a large number of micro-cracks in the sliding surface. (Japan) Oguchi Yoshio observed by scanning electron microscopy highlights the danger of coal melt traces, and that this is due to volcanic invasion of coal secondary heating results. China’s Fushun Coal Research Institute electron microscope room also published in 1978, “the application of scanning electron microscopy of the pore structure of coal,” the article.
