煤矿采空区的形成及地球物理勘探方法的选择

The Formation of Gob Areas of Coal Mine and The Selection of Geophysical Exploration Methods

从煤矿采空区的形成机理入手,分别从电性、地震波、密度等方面分析了采空区及上覆岩层的地球物理特征。以不同的物性特征为基础,根据探测原理、方法特点系统总结了目前可用于煤矿采空区探测的地球物理勘探方法。因采空区的复杂性和无规律性,结合实际情况提出了采空区探测应遵循的原则,科学合理地选择适宜的探测方法对其进行探测。

In this paper,it starts with the formation mechanism of gab area,and analyses geophysical characteristics about gob area and overlying strata from electrical property,seismic waves,density and other aspects. Based on the different geophysical characteristics,the exploration methods which can be used for detecting gob areas of coal mine at present aresystematically summarized from detecting principle,method characteristic and others. For the complexity and no regularity of gob areas,combined with the actual situation,the paper proposes the detection of gob areas should be followed principles,selects suitable method scientifically and properly for prospecting.
