综合物探方法在煤矿采空区探测中的应用

    Application of comprehensive geophysical prospecting in investigation of coal mine goaves

    • 摘要: 辽阳灯塔市铧子镇—西大窑一带存在较多煤矿小窑采空区,分布于村镇及周边,对地面房屋建筑和居民生活形成极大威胁,矿区周围一定范围内植被稀疏,大量采煤粉碴随意堆存,给生态环境带来严重破坏。但单一方法调查采空区具有局限性,难以彻底消除干扰和观测误差,本文从物探方法抗干扰性和有效性方面进行了选择和探索,运用的方法包括重力测量、高密度电法和浅层地震,经过钻孔验证,取得的效果较好。

       

      Abstract: There are many small coal mine goaves in Huazi Town-Xidayao Town in Dengta City, Liaoyang City, Liaoning Province. They are distributed in villages and towns and their surrounding areas, posing great threats to the ground buildings and resident life. Furthermore, the vegetation around the mining area is sparse, and a large amount of coal slag has been piled up at will, which causes serious damage to the ecological environment. However, owing to the limitations of a single geophysical method, it is difficult to completely eliminate interference and observation errors through the goaf investigation using a single geophysical method. Based on the selection and exploration of geophysical methods from the aspects of anti-interference and effectiveness, this study conducted the coal mine goaves in the study area by applying the geophysical prospecting methods including gravity survey, high-density resistivity method, and shallow seismic reflection method. As verified through drilling, ideal results were achieved.
