该文以阳泉市某采空区场地为研究对象,通过资料收集、地质调查、地球物理探测、室内外岩土试验和水文地质测试等方法,对采空区的形态及性质进行了系统的研究,认为收集开采资料和调查访问是工程地质测绘工作中不可忽视的非常重要的一个环节;直达波地震CT技术揭示了波在经过采空区其振幅和波速明显衰减的作用机理,有效地探测了地下采空区的形态分布;钻探技术验证了测绘和物探的结果;注水试验可根据岩土层渗透性的大小确定上覆岩土体的垮落压密程度,系统的工作获得了准确的第一手资料,为采空区的分布情况及稳定性等方面的研究奠定了基础。
This paper takes a mined-out area in Yangquan as the research object. Through the methods of data collection, geological survey, geophysical exploration, indoor and outdoor geotechnical test and hydrogeological test, the paper studies the morphology and properties of goaf , That the collection of mining information and survey visit is the geological mapping work can not be ignored in a very important part of the direct wave seismic CT technology reveals the wave in the goaf through its amplitude and wave velocity significantly decay mechanism of action to effectively detect Underground mined area; the drilling technology verifies the results of mapping and geophysical exploration; water injection test can determine the degree of collapse and collapse of the overburden rock mass according to the permeability of rock and soil layers; First-hand information for the gob of the distribution and stability of the study laid the foundation.
