【摘要】 研究了煤层裂隙探测的地震波形分类技术原理,即根据地震资料,在一定时窗范围内统计地震波的几何形状、频率、能量变化快慢及各种地震属性,从而在剖面上和平面上划分各种地震属性特征总和相近的区域,通过钻孔和已知裂隙资料的标定,探测煤层裂隙.利用地震波形分类技术对淮南潘三矿煤层裂隙的探测结果表明,这种方法行之有效,可以为矿井瓦斯危险性预测提供科学依据.更多还原

【Abstract】 The principle of seismic waveform classification technique for detection of coal seam fracture was studied.Based on seismic data,geometric shape,frequency,speed of energy change and all kinds of seismic attributes of seismic wave can be counted in time window limits.Thereby the close area of summation of all kinds of seismic attributes character can be ploted at section and peace planes.Then coal seam fracture can be detected after demacation of drill and known frature datum.Through the detection of coal seam fracture in Pansan mine of Huainan mining group company,the results show that seismic waveform classification technique is effective,which offers scientific basis for detection of mine gas danger.更多还原
