【摘要】 把多波多分量地震反射法引入到煤矿井下,针对陷落柱的特征及陷落柱与周围煤体之间的明显物性界面,从理论和实例上对多波多分量地震反射法探测陷落柱的可行性进行了探讨。从实例的揭露验证情况对比可知,利用井下多波多分量地震反射法超前探测巷道掘进面前方的陷落柱是可行有效的一种新方法。更多还原

【Abstract】 In this paper,exploration was made on the feasibility of apllying multi-wave multi-component reflection servey for subsided column detection based on the theory and actual examples by introducing multi-wave multi-component reflection servey in coal mine and in accordance with the characteristics of subsided columns and the marked interface between the subsided column and coal body around it.It can be seen from the revealatory test and veritification by actual examples that it is a feasible and effective new method to apply multi-wave multi-component reflection servey for detecting subsided columns in front of the heading face.更多还原
