摘要
为了确定淮南煤田一例三维地震反射波异常区性质,通过三维地震精细解释圈定异常区空间形态,根据地面钻探探查分析异常区物质组成,采用井下探查确保采掘工程安全不受异常区影响,形成了陷落柱井上下综合探查技术。提出了包含岩心分析、预想柱状对比、煤层埋深插值计算及地层演化特征分析的陷落柱判识技术。研究表明:3#陷落柱具有地层层序相对正常,部分地层相对完整,胶结程度好,未发现大段堆石体与空腔等特征。
In order to determine the characteristics of an abnormal area of three dimensional seismic reflection wave in Huainan Coal Field, fine interpretation was carried out to frame the space form, a ground borehole was drilled to detect rock mass composition, underground detection was used to ensure the mining safety. Karst collapse column comprehensive exploration technique was formed by these methods. Core analysis, expect formation comparative analysis, coal seam depth interpolation calculation and stratum evolution were applied to determine the characteristics. Study results show that the No. 3 column has characteristics including relatively normal stratum sequence, relatively complete rock mass, high degree of consolidation, no large disorderly rock mass or cavity.
