采空区二维超声波物理模型实验研究
|
摘要
由于对资源矿产的过度开采使得矿山地区(尤其是煤矿)出现了采空区,从而引起地表塌陷等地质灾害。为了深入了解地震方法在采空区调查中的应用效果,从超声波物理模型实验研究出发,论述了物理模型的原理和制作,研究了采空区的地震波场特征,并利用W inse is软件对所采集的二维超声波实验数据进行了处理。由叠偏剖面推断的采空区的位置与实际模型相符,从而验证了超声波采空区物理模型试验是有效的、可信的;同时可以为实际探测采空区提供进一步的理论依据。
Because of resource mining excessively,it appears many caves in mine areas.So the geologic disaster of earth surface sinking is caused by the caves.In order to understand deeply seismic application in makinga survey of cave.The paper starts with the experiment study on the 2D ultrasonicphysics model;it discusses principle and makings about the physics model and studys characters of seismic wave field of cave.The dates gathered from the experiment are processed by the Winseis software.We can conclude that the cave'sposition is matching with real model from the overlapped migration section.Consequently it validates that the experiment is valid and believable;At the same time it At the same time the article can provide further theories argument for pactical surveying the cave.
