综合物探技术在煤矿陷落柱中的探测应用分析

Analysis and application of comprehensive geophysical exploration technology in the collapsed column of mine

通过地震勘探的方式可勘察煤矿中陷落柱的分布情况,但由于陷落柱中含水量等情况有着较大的差异,仅使用这一单一的物探技术不能满足煤矿安全生产的需求。通过采用综合物探技术,如瞬变电磁探测技术、可控源音频大地电磁探测技术、地震勘探技术,可取得较好的煤矿陷落柱探测效果。以梧桐庄矿中陷落柱实际探测需求出发,通过采用综合物探技术对其进行勘察,并将得到结果与实际工程钻探结果对比分析,结果表明,综合物探技术和钻探结果吻合度较高,为探测陷落柱提供了一个全新思路。

Based on the use of seismic exploration,we can detect the distribution of subsided columns in coal mines,but there are great differences due to the water content in subsided columns. Only using this single geophysical technology can not meet the needs of coal mine safe production. Using integrated geophysical technology（ transient electromagnetic detection technology,controlled source audio frequency magnetotelluric exploration technology,seismic exploration technology）,the technology achieves better detection results of coal mine collapsed column. Based on collapsed column in the actual detection requirements of Wutongzhuang Mine,through the use of integrated geophysical techniques,and the results obtained with the actual drilling results contrast analysis,with the high degree of coincidence of comprehensive geophysical prospecting and drilling results,providing reference for the detection of subsided column.
