浅层地震在煤矿采空区勘查中应注意的问题

SOME PROBLEMS WORTHY OF ATTENTION IN THE APPLICATION OF SHALLOW EARTHQUAKE TO THE DETECTION OF GOAF

在对煤矿采空区的勘查中,浅层地震可谓是首选的地球物理方法之一,其以分辨能力强、探测效果好等优势被广泛的应用于该领域,尤其是对同时存在多层采空区的情况更显示其优越性,但对比其他地球物理方法又具有野外作业要求高、资料处理解释技术难度大等特点,所以在这些方面更应以严谨的态度对待。根据以往的工作成果,对该方法的野外采集技术、资料处理与解释等方面提出了一些个人的见解。

In the exploration of the coal goaf, shallow earthquakes can be regarded as one of the preferred geophysical methods. Its advantages such as high resolution and good detection results have been widely used in goaf detection, and its superiority is especially ob- vious in the exploration of multi - layer goal; nevertheless, its high requirement in field work and difficult data processing as compared with other geophysical methods should be given much careful and prudent attention. Based on previous achievements, the authors pres- ent some personal opinions concerning the field acquisition technique and data processing and interpretation of this method.
