| 1 | 井下槽波地震勘探——预防煤矿灾害的一种地球物理方法显示文摘当在煤层中激发地震波时,由于顶、底板围岩速度明显高于煤层中地震波的传播速度,当地震波入射角大于临界角时会发生全反射,经过多次全反射混合叠加,在煤层中形成槽波.槽波是一种围限波,它最大的特点是频散现象,槽波在煤层中传播时还具有速度低、衰减弱等特点,因此可以用来探测煤层中的采空区、断层等地质构造.本文初步阐述了槽波地震勘探技术的研究现状,槽波的形成,槽波的特点、槽波地震勘探的工作方法以及应用实例等内容,并基于其特点对槽波地震勘探技术作出了展望. | 胡国泽 滕吉文 皮娇龙 王伟 乔勇虎 | 2013 | 地球物理学进展2013，28，1： | 120 |

| 4 | Coal–rock interface detection on the basis of image texture features显示文摘Based on the stability and inequality of texture features between coal and rock,this study used the digital image analysis technique to propose a coal–rock interface detection method.By using gray level co-occurrence matrix,twenty-two texture features were extracted from the images of coal and rock.Data dimension of the feature space reduced to four by feature selection,which was according to a separability criterion based on inter-class mean difference and within-class scatter.The experimental results show that the optimized features were effective in improving the separability of the samples and reducing the time complexity of the algorithm.In the optimized low-dimensional feature space,the coal–rock classifer was set up using the fsher discriminant method.Using the 10-fold cross-validation technique,the performance of the classifer was evaluated,and an average recognition rate of 94.12%was obtained.The results of comparative experiments show that the identifcation performance of the proposed method was superior to the texture description method based on gray histogram and gradient histogram. | Sun Jiping Su Bo | 2013 | International Journal of Mining Science and Technology2013，23，5： | 15 |
| 5 | Advanced prediction for multiple disaster sources of laneway under complicated geological conditions显示文摘The driving safety in the laneway is often controlled by multiple disaster sources which include fault fracture zone, water-bearing body, goaf and collapse column. The advanced prediction of them has become a hotspot. Based on analysis of physical characteristics of the disaster sources and comparative evaluation of accuracy of the main advanced geophysical detection methods, we proposed a comprehen- sive judging criterion that tectonic interface can be judged by the elastic wave energy anomaly, strata water abundance can be discriminated by apparent resistivity response difference and establish a reason- able advanced prediction system. The results show that the concealed disaster sources are detected effec- tively with the accuracy rate of 80% if we use advanced prediction methods of integrated geophysics combined with correction of seismic and electromagnetic parameters, moreover, applying geological data, we may then distinguish types of the disaster sources and fulfill the qualitative forecast. Therefore, the advanced prediction system pays an important referential and instructive role in laneway driving project. | Wang Bo Liu Shengdong Liu Jing Huang Lanying Zhao Ligui | 2011 | Mining Science and Technology2011，21，5： | 5 |
| 6 | 基于F-K变换的煤层透射槽波信号提取显示文摘槽波勘探是井下地震勘探的主要方式之一,能够在较大范围内探测出煤层中的断层、陷落柱、溶洞等地质异常体,对煤矿的安全生产具有重要作用。在透射法槽波勘探中,需要寻找出槽波的阻断位置以对断层进行定位。然而井下地震信号中波场成分复杂、信噪比低,槽波信号会被噪声所遮盖而很难寻找出具体的阻断位置。针对这一问题,根据槽波的频散特性,利用二维傅里叶变换将地震信号转换到F-K域并对其进行滤波,以消弱噪声和其它波场成分。实际工程中的应用效果表明,在经过F-K滤波后的地震数据中,可以较为容易的识别出槽波的阻断位置。 | 王季 | 2011 | 煤矿安全2011，42，7： | 4 |
