| 摘 要： | 断层、老窑、陷落柱和煤层缺失等地质异常是煤矿潜在的地质灾害,因地质异常不清造成事故和生产停顿的事,在煤矿时有发生。我们根据弹性波对不同地质体之间密度和波传播速度等物性差异的敏感性,分析了纵波、横波、瑞利波和槽波在地层中的传播特性,研究了弹性波地震探测技术。包括探测仪器研制、资料采集和数据处理技术研究。并应用该技术从地面、井下巷道和工作面侧壁,在许多煤矿进行地质异常探测试验,取得明显效果,为煤矿建井、掘进和开采提供了可靠的地质保障,并为煤矿装备了有力的探测手段。

| Abstract: | It is a sort of potentian geological casualty in mine that there are faurlts, goals, no coal pit, fading of coal and so on, mine sometimes bring out accident and stoping working because the geological anomalous have not clear located. According to the sensitivity of different geological body physical character difference in density and elastic wave speed. We have analysed the propagating feafure of compressional wave, shear wave, Rayleigh wave and channel wave in strata and developed elastic seismic prospecting technique that includes device manufacturing, data acquiring and data processing. The technique have been used in many mines for detecting gete geologic anomalous from surface, underground heading and working face rib and got a great effect. It provides with poswerful exploration method for mines. |
