ANALYSIS ON THE ABSORPTING CHARACTERISTICS OF ELECTROMAGNETIC WAVE IN COAL SEAM WITH SOFT COAL, ROOF AND FLOOR
-
摘要: 通过对梁家煤矿两个工作面的坑透试验研究,获得了"三软煤层"的电磁波吸收系数β;应用CT技术处理得到了工作面吸收色谱图,分析了"三软煤层裂隙、构造的吸收异常特征,取得了较好的地质效果。Abstract: Based on the tunnel transmission tests on both working faces in Liangjia mine,the absorpting coefficient β of electromagnetic wave in coal seam with soft coal,roof and floor is found;using the absorpting chromatograph charts of working faces obtained by the CT technique processing,the absorption abnormal characteristics of fractures and structures in coal seam with soft coal,roof and floor are analyzed,and the better geological effectiveness is obtained.
